  text: In this paper we propose a novel low-power receiver architecture which uses
    a direct-detection receiver in combination with a 2.44 GHz 13 bit Barker Code
    SAW correlator for improvement of co-channel interference. Furthermore, to improve
    receiver sensitivity, a narrowband baseband correlator which uses pulse position
    modulation (PPM) is proposed. The receiver can be used as a Wake-up Receiver (WuRx)
    in Wireless Sensor Networks (WSN) to minimize the power dissipation and provide
    asynchronous and on-demand data communication. We present a rigorous analysis
    of the receiver. It shows that the RF front-end (SAW correlator and envelope detector)
    alone suffers from poor sensitivity due to the high baseband bandwidth and the
    absence of an RF low noise amplifier. However, by adding the narrowband correlator
    with an innovative Pulse Position Modulation (PPM) scheme, the overall sensitivity
    of the receiver reaches -63.1 dB with an improvement of 17.7 dB due to the use
    of the narrowband correlator that reduces the baseband bandwidth from 50 to 0.84
    MHz. By scaling the narrowband correlator bandwidth further down, the receiver
    sensitivity can be further improved.

  text: Fault effect simulation is a well-established technique for the qualification
    of robust embedded software and hardware as required by different safety standards.
    Our article introduces a Virtual Prototype based approach for the fault analysis
    and fast simulation of a set of automatically generated and target compiled software
    programs. The approach scales to different RISC-V ISA standard subset configurations
    and is based on an instruction and hardware register coverage for automatic fault
    injections of permanent and transient bitflips. The analysis of each software
    binary evaluates its opcode type and register access coverage including the addressed
    memory space. Based on this information dedicated sets of fault injected hardware
    models, i.e., mutants, are generated. The simulation of all mutants conducted
    with the different binaries finally identifies the cases with a normal termination
    though executed on a faulty hardware model. They are identified as a subject for
    further investigations and improvements by the implementation of additional hardware
    or software safety countermeasures. Our final evaluation results with automatic
    C code generation, compilation, analysis, and simulation show that QEMU provides
    an adequate efficient platform, which also scales to more complex scenarios.

  text: Low-power receivers use direct-detection receiver architecture for its design
    simplicity and its low power dissipation. However, the direct-detection based
    receivers suffer from co-channel interference which significantly degrades the
    communication reliability. Co-channel interference robustness can be improved
    by using a BPSK Barker code modulated Surface Acoustic Wave (SAW) correlator as
    a prior stage to the RF direct detection circuit. This paper reports in details
    the design, fabrication and measurements of a 2.45 GHz SAW correlator with 13
    bits length Barker code. The device is fabricated on Lithium Niobate LiNbO3 substrate
    and it is composed of an input non-coded Inter Digital Transducers (IDT), a Piezoelectric
    substrate and an output coded IDT. The device wavelength λ is set to 1.6 μm, considering
    a phase velocity of the wave equal to 3970 m.s-1. Several configurations of the
    device were designed and fabricated, particularly varying the aperture and the
    non-coded IDT length to find out the optimal device configuration. All devices
    were found to operate with Insertion Loss (IL) ranging from 12 to 15 dB at 2.45
    GHz with a tip probing measurement setup, while a packaged sample has an IL of
    12.45 dB at 2.44 GHz mounted on a PCB with external 50 Ω LC matching network.
    Additionally, time-domain measurement for the packaged device shows that the output
    has a correlation peak with a peak-to-side-lobe (PSL) ratio of 4:1 for a -0.5
    dBm input BPSK Barker code signal.

  text: Novel analog-to-digital converter (ADC) architectures are motivated by the
    demand for rising sampling rates and effective number of bits (ENOB). The main
    limitation on ENOB in purely electrical ADCs lies in the relatively high jitter
    of oscillators, in the order of a few tens of fs for state-of-the-art components.
    When compared to the extremely low jitter obtained with best-in-class Ti:sapphire
    mode-locked lasers (MLL), in the attosecond range, it is apparent that a mixed
    electrical-optical architecture could significantly improve the converters' ENOB.
    We model and analyze the ENOB limitations arising from optical sources in optically
    enabled, spectrally sliced ADCs, after discussing the system architecture and
    implementation details. The phase noise of the optical carrier, serving for electro-optic
    signal transduction, is shown not to propagate to the reconstructed digitized
    signal and therefore not to represent a fundamental limit. The optical phase noise
    of the MLL used to generate reference tones for individual slices also does not
    fundamentally impact the converted signal, so long as it remains correlated among
    all the comb lines. On the other hand, the timing jitter of the MLL, as also reflected
    in its RF linewidth, is fundamentally limiting the ADC performance, since it is
    directly mapped as jitter to the converted signal. The hybrid nature of a photonically
    enabled, spectrally sliced ADC implies the utilization of a number of reduced
    bandwidth electrical ADCs to convert parallel slices, resulting in the propagation
    of jitter from the electrical oscillator supplying their clock. Due to the reduced
    sampling rate of the electrical ADCs, as compared to the overall system, the overall
    noise performance of the presented architecture is substantially improved with
    respect to a fully electrical ADC.

  text: The effect of phase noise introduced by optical sources in spectrally-sliced
    optically enabled DACs and ADCs is modeled and analyzed in detail. In both data
    converter architectures, a mode-locked laser is assumed to provide an optical
    comb whose lines are used to either synthesize or analyze individual spectral
    slices. While the optical phase noise of the central MLL line as well as of other
    optical carriers used in the analyzed system architectures have a minor impact
    on the system performance, the RF phase noise of the MLL fundamentally limits
    it. In particular, the corresponding jitter of the MLL pulse train is transferred
    almost one-to-one to the system-level timing jitter of the data converters. While
    MLL phase noise can in principle be tracked and removed by electronic signal processing,
    this results in electric oscillator phase noise replacing the MLL jitter and is
    not conducive in systems leveraging the ultra-low jitter of low-noise mode-locked
    lasers. Precise analytical models are derived and validated by detailed numerical
    simulations.

  text: A 28 Gbps NRZ bang-bang clock and data recovery (CDR) chip for 100G PSM4 is
    presented. It exhibits an adaptable loop filter transfer function with independently
    tunable proportional and integral parameters. This allows to optimize the jitter
    transfer, jitter tolerance, and locking range of the CDR according to system requirements.
    The CDR represents a key component for a single-chip 8-channel electronic-photonic
    PSM4 transceiver. A CDR chip was manufactured in a 0.25 μm monolithic photonic
    BiCMOS technology. The core chip area is 0.51 mm 2 and it dissipates 330 mW from
    2.5 V and 3.3 V power supplies.

  text: Recently it has been demonstrated that an optoelectronic phase-locked loop
    (OEPLL) using a mode-locked laser as a reference oscillator achieves significantly
    lower phase noise than conventional electronic frequency synthesizers. In this
    paper a concept for an OEPLL-based frequency synthesizer is presented and it is
    investigated how it can be used as a local oscillator (LO) for THz transceivers
    in order to improve the signal quality in THz wireless communications. The concept
    of the OEPLL is presented and it's measured phase noise is compared to the phase
    noise of a laboratory-grade electronic frequency synthesizer. The measured phase
    noise spectra of both synthesizers at 10 GHz are then used to model LO phase noise
    at 320 GHz. Based on models of generic zero-IF transmit and receive frontends,
    THz signals with different modulation formats and Baud rates are simulated at
    system level using the modeled LO phase noise for the two LO approaches. Finally,
    the results are compared.

  text: This paper presents an ultra-wideband and ultra-low noise frequency synthesizer
    using a mode-locked laser as its reference. The frequency synthesizer can lock
    in the frequency range from 2 GHz to 20 GHz on any harmonic of a mode-locked laser
    optical pulse train. The integrated rms-jitter (1 kHz-100 MHz) of the synthesizer
    is less than 5 fs in the frequency range from 4 GHz to 20 GHz with a typical value
    of 4 fs and a minimum of 3 fs. This is the first reported wideband phase locked
    loop achieving sub-10 fs rms-jitter for offset frequencies larger than 1 kHz.

  text: This paper presents a broadband track-and-hold amplifier (THA) based on switched-emitter-follower
    (SEF) topology. The THA exhibits both large- and small-signal bandwidth exeeding
    60 GHz. It achieves an effective number of bits (ENOB) of 7 bit at 34 GHz input
    frequency and an ENOB of >5 bit over the whole input frequency bandwidth at sampling
    rate of 10 GS/s. Much higher sampling rates are possible but lead to somewhat
    worse performance. The chip was fabricated in a 130 nm SiGe BiCMOS technology
    from IHP (SG13G2). It draws 78 mA from a -4.8 V supply voltage, dissipating 375
    mW.

  text: In this paper we present the system and circuit level analysis and feasibility
    study of applying microwave Radio Frequency Identification (RFID) systems with
    multipleinput multiple-output (MIMO) reader technology for tracking machining
    tools in multipath fading conditions of production environments. In the proposed
    system the MIMO reader interrogates single-antenna tags, and a high RFID frequency
    of 5.8 GHz is chosen to reduce the size of the reader's antenna array. According
    to the requirements dictated by the performed system analysis at 5.8 GHz, a low
    power fully integrated analog frontend (AFE) is designed and fabricated in a standard
    65-nm CMOS technology for low power passive transponders. Performance of the Differential
    Drive Rectifier (DDR) topology as the core of the energy harvesting unit is investigated
    in detail. A multi-stage DDR power scavenging unit is dimensioned to provide a
    1.2 V rectified voltage for 20-30 kQ load range, with a high power conversion
    efficiency (PCE) for high frequency and low input power level signals. The rectified
    voltage is then converted to a 1 V regulated voltage for the AFE and the baseband
    processor with 30 to 50 μW of estimated power consumption. Transistors with standard
    threshold voltage (VT) have been used for implementation. Measurements of the
    fabricated multi-stage configuration of the circuit show a maximum PCE of 68.8%
    at -12.46 dBm, and an input quality factor (Q-factor) of approximately 10. Amplitude-shift
    keying (ASK) demodulator and backscattering modulator with 80% modulation index,
    operating according to EPC-C1G2 protocol are applied for data transfer. The AFE
    consumes less than 1 μW in the reading mode. The AFE tag chip is 0.55 × 0.58 mm

  text: In this paper we present a new system concept for an optoelectronic wireless
    phased array system. Like in a conventional phased array system with optical carrier
    distribution, optical fibers are used to distribute the carrier from the basestation
    to the wireless frontends. However in contrast to prior concepts, we propose to
    use an optical IQ return path from the wireless frontends back to the basestation.
    Furthermore, we reuse the optical carrier signal for the IQ return path which
    allows to avoid local oscillator lasers in the wireless frontends and reduces
    the hardware effort significantly. The system concept allows to integrate all
    components of an optoelectronic wireless frontend in a single chip using silicon
    photonics technology.

  text: Embedded systems require a high energy efficiency in combination with an optimized
    performance. As such, Bit Manipulation Instructions (BMIs) were introduced for
    x86 and ARMv8 to improve the runtime efficiency and power dissipation of the compiled
    software for various applications. Though the RISC-V platform is meanwhile widely
    accepted for embedded systems application, its instruction set architecture (ISA)
    currently still supports only two basic BMIs.We introduce ten advanced BMIs for
    the RISC-V ISA and implemented them on Berkeley's Rocket CPU [1], which we synthesized
    for the Artix-7 FPGA and the TSMC 65nm cell library. Our RISC-V BMI definitions
    are based on an analysis and combination of existing x86 and ARMv8 BMIs. Our Rocket
    CPU hardware extensions show that RISC-V BMI extensions have no negative impact
    on the critical path of the execution pipeline. Our software evaluations show
    that we can, for example, expect a significant impact for time and power consuming
    cryptographic applications.

    die CPU angeschlossene IO-Geräte. Wir demonstrieren die Funktionalität der Methode
    anhand eines Versuchsaufbaus, bei dem eine Schließsystemkontrolle mittels serieller
    UART-Schnittstelle an einen RISC-V-Prozessor angebunden ist. Dieses Szenario zeigt,
    dass ein unberechtigter Zugriff auf die UART-Schnittstelle frühzeitig aufgedeckt
    und ein Angriff auf eine Zugangskontrolle somit endeckt werden kann. '

  text: It its current Version 3.1.0 QEMU supports RISC-V RV32GC and RV64GC software
    emulation in user and full system mode. We will first give an overview of the
    current state of the QEMU RISC-V implementation. Thereafter, we will present the
    DecodeTree tool, which will be available with the next QEMU release. DecodeTree
    is a code generator included in QEMU that can generate the program logic for extracting
    and decoding opcodes and operands from a formal instruction list of the target
    architecture. This enables the structured implementation of just-in-time compilations
    to guarantee that the QEMU implementation meets the ISA specification. As such,
    we completely replaced the existing RISC-V RV32GC and RV64GC implementations by
    DecodeTree generations in the next official QEMU release, which is expected in
    spring 2019. We will demonstrate the DecodeTree applications by the example of
    RISC-V ISA subset configurations.

  text: An octave-band voltage-controlled oscillator is phase-locked on the envelope
    of the pulse train from a mode-locked laser. The locking scheme employs a balanced
    Mach-Zehnder modulator with two photodiodes as a phase detector. The phase.locked
    loop has a loop bandwidth of approximately 1MHz and an in-band phase noise of
    approximately -135dBc/Hz at all frequencies. The integrated jitter from 1kHz to
    100MHz is 21fs, 18.3fs and 13.8fs at 5.016GHz, 7.6GHz and 10.032GHz carrier frequencies,
    respectively. To the authors' knowledge, this is the best jitter performance reported
    for a PLL with MZM-based phase detection and the first reported PLL of this type
    featuring an octave-band frequency range.
