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: 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: 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: AbstractThe derivative concept plays a major
role in economics. However, its use in economics is very heterogeneous, sometimes
inconsistent, and contradicts students’ prior knowledge from school. This applies
in particular to the common economic interpretation of the derivative as the amount
of change while increasing the production by one unit. Hence, in calculus courses
for economics students, learners should acquire an understanding of the derivative
that is mathematically acceptable and connected to their prior knowledge, but
which also takes into account its practical use in economics. In this paper we
first develop a theoretical model describing such an understanding of the derivative
for economics students. We then present an exploratory study investigating the
extent to which economics students have such an understanding after their calculus
course. The results indicate that many of them might not have acquired this kind
of understanding, in particular concerning the common economic interpretation
of the derivative. The study furthermore yields possible gaps in students’ understanding
and possible misconceptions.
