A balanced optical microwave phase detector (BOMPD) is implemented using a balanced Mach-Zehnder modulator and is employed to discriminate the phase difference between the envelope of the optical pulses and the microwave oscillator. It is shown mathematically that the inherent nonlinear properties of BOMPD with respect to the microwave excitation amplitude can be used for interharmonic locking. The characteristic functions of the phase detector for interharmonic locking are derived analytically and are compared with the measurement results. An opto-electronic phase-locked loop (OEPLL) is demonstrated whose output frequency locks on interharmonics of the MLL repetition rate when an appropriate modulator bias and sufficient RF amplitude are applied. Thus, for the first time theory and experiment of reliable locking on interharmonics of the repetition rate of a MLL are presented.</jats:p>","lang":"eng"}],"issue":"5","publication":"Optics Express","doi":"10.1364/oe.451894","language":[{"iso":"eng"}],"article_number":"7763","intvolume":"        30","publication_status":"published","date_updated":"2025-03-10T13:27:46Z","author":[{"last_name":"Bahmanian","first_name":"Meysam","full_name":"Bahmanian, Meysam","id":"69233"},{"id":"13256","first_name":"Christian","last_name":"Kress","full_name":"Kress, Christian"},{"id":"37144","first_name":"J.

As the Nyquist signal has a rectangular bandwidth, it can be multiplexed in the wavelength domain without any guardband as a part of a Nyquist-WDM superchannel. These superchannels can be additionally multiplexed in space and polarization. Thus, the presented demonstration can open a new possibility for the detection of multidimensional parallel data signals with silicon photonics. No external pulse source is needed for the receiver, and frequency-time coherence is used to sample the incoming Nyquist signal with orthogonal sinc-shaped Nyquist pulse sequences. All parameters are completely tunable in the electrical domain. The feasibility of the scheme is demonstrated through a proof-of-concept experiment over the entire C-band (1530 nm–1560 nm), employing a 24 Gbaud Nyquist QPSK signal due to experimental constraints on the transmitter side electronics. However, the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can process Nyquist signals of 90 GHz optical bandwidth, suggesting a possibility to detect symbol rates up to 90 GBd in an integrated Nyquist receiver.</jats:p>"}],"issue":"8","publication":"Optics Express","doi":"10.1364/oe.454163","article_number":"13776","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2025-07-02T12:19:40Z","intvolume":"        30","title":"Reconfigurable and real-time high-bandwidth Nyquist signal detection with low-bandwidth in silicon photonics","year":"2022","publication_identifier":{"issn":["1094-4087"]},"author":[{"first_name":"Arijit","last_name":"Misra","full_name":"Misra, Arijit"},{"id":"13256","full_name":"Kress, Christian","orcid":"0000-0002-4403-2237","last_name":"Kress","first_name":"Christian"},{"full_name":"Singh, Karanveer","first_name":"Karanveer","last_name":"Singh"},{"full_name":"Meier, Janosch","first_name":"Janosch","last_name":"Meier"},{"full_name":"Schwabe, Tobias","first_name":"Tobias","last_name":"Schwabe","id":"39217"},{"full_name":"Preussler, Stefan","last_name":"Preussler","first_name":"Stefan"},{"full_name":"Scheytt, J.

However, their role in virtual prototyping and the correlation to later steps in the design process need further investigation. We introduce a metric for RISC-V instruction and register coverage for binary software. The metric measures if RISC-V instruction types are executed and if GPRs, CSRs, and FPRs are accessed. The analysis is applied by the means of a virtual prototype which is based on an abstract instruction and register model with direct correspondence to their bit level representation. In this context, we analyzed three different openly available test suites: the RISC-V architectural testing framework, the RISC-V unit tests, and programs which are automatically generated by the RISC-V Torture test generator. We discuss their tradeoffs and show that by combining them to a unified test suite we can arrive at a 100% GPR and FPR register coverage and a 98.7% instruction type coverage.","lang":"eng"}],"related_material":{"link":[{"url":"https://ieeexplore.ieee.org/document/9399723","relation":"confirmation"}]},"_id":"32125","publisher":"VDE","language":[{"iso":"eng"}],"user_id":"5603","author":[{"id":"5603","full_name":"Adelt, Peer","first_name":"Peer","last_name":"Adelt"},{"id":"25260","full_name":"Koppelmann, Bastian","last_name":"Koppelmann","first_name":"Bastian"},{"full_name":"Müller, Wolfgang","first_name":"Wolfgang","last_name":"Müller","id":"16243"},{"id":"37144","last_name":"Scheytt","first_name":"Christoph","full_name":"Scheytt, Christoph"}],"publication_identifier":{"isbn":["978-3-8007-5500-4"]},"conference":{"start_date":"2021-03-18","end_date":"2021-03-19"},"year":"2021","title":"Register and Instruction Coverage Analysis for Different RISC-V ISA Modules","status":"public","publication_status":"published","date_updated":"2022-06-23T11:54:16Z"},{"place":"Munich, DE","date_created":"2022-06-23T12:07:10Z","keyword":["QEMU","aiT","Zeitannotation","WCET"],"type":"conference","department":[{"_id":"58"}],"publication":"MBMV 2021 - Methods and Description Languages for Modelling and Verification of Circuits and Systems; GMM/ITG/GI-Workshop","citation":{"mla":"Adelt, Peer, et al. “QEMU zur Simulation von Worst-Case-Ausführungszeiten.” <i>MBMV 2021 - Methods and Description Languages for Modelling and Verification of Circuits and Systems; GMM/ITG/GI-Workshop</i>, VDE, 2021.","apa":"Adelt, P., Koppelmann, B., Müller, W., &#38; Scheytt, C.

The charge sampling technique is mathematically analyzed in detail and compared to conventional switched-capacitor sampling. The mathematical analysis allows to predict the sampler bandwidth as well as the degradation of sampling precision due to analog circuit impairments such as integrator gain error, integration capacitor leakage, hold-mode droop, thermal noise, and clock jitter. Furthermore, design, simulation, and measurement results of an ultra-broadband charge sampler IC in SiGe BiCMOS technology are presented. The charge sampler IC achieves a 1dB bandwidth of 70 GHz. A resolution of better than 5.9 effective number of bits (ENOB) is measured from 0 to 70 GHz at a sampling rate of 5 GS/s.

No external pulse source is needed and frequencytime coherence is used to sample the incoming Nyquist OTDM signal with orthogonal sinc-shaped Nyquist pulse sequences using Mach-Zehnder modulators. All the parameters such as bandwidth and channel selection are completely tunable in the electrical domain. The feasibility of this scheme is demonstrated through a demultiplexing experiment over the entire C-band (1530 nm - 1550 nm), employing 24 Gbaud Nyquist QAM signals due to experimental constraints on the transmitter side. However, the silicon Mach-Zehnder modulator with a 3-dB bandwidth of only 16 GHz can demultiplex Nyquist pulses of 90 GHz optical bandwidth suggesting a possibility to reach symbol rates up to 90 GBd in an integrated Nyquist transceiver.

The spectral slices are coherently detected using a frequency comb as a multi-wavelength local oscillator (LO) and stitched together by digital signal processing (DSP). For high-quality signal reconstruction, we have implemented a maximum-ratio combining (MRC) technique based on precise calibration of the complex-valued opto-electronic transfer functions of all detection paths. In a proof-of-concept experiment, we demonstrate the viability of the scheme by implementing a four-channel system that offers an overall detection bandwidth of 140 GHz. Exploiting a femtosecond laser with precisely known pulse shape for calibration along with dynamic amplitude and phase estimation, we reconstruct 100 GBd QPSK, 16QAM and 64QAM optical data signals. The reconstructed signals show improved quality compared to that obtained with a single high-speed intradyne receiver, while the electronic bandwidth requirements of the individual coherent receivers are greatly reduced."}],"page":"1-1","_id":"29209","publisher":"Institute of Electrical and Electronics Engineers (IEEE)","user_id":"44271","status":"public","citation":{"short":"D.

In addition to ultra-broadband signal processing, it allows leveraging ultra-low jitter mode-locked lasers and thus increasing the aperture jitter limited effective number of bits at high analog signal frequencies. In this paper, we review our recent progress towards optically enabled time- and frequency-interleaved analog-to-digital converters, as well as their monolithic integration in electronic-photonic integrated circuits. For signal frequencies up to 65 GHz, an optoelectronic track-and-hold amplifier based on the source-emitter-follower architecture is shown as a power efficient approach in optically enabled BiCMOS technology. At higher signal frequencies, integrated photonic filters enable signal slicing in the frequency domain and further scaling of the conversion bandwidth, with the reconstruction of a 140 GHz optical signal being shown. We further show how such optically enabled data converter architectures can be applied to a nonlinear Fourier transform based integrated transceiver in particular and discuss their applicability to broadband optical links in general."}],"publication":"IEEE Open Journal of the Solid-State Circuits Society","volume":1,"user_id":"44271","_id":"29211","publisher":"Institute of Electrical and Electronics Engineers (IEEE)","page":"209-221","status":"public","project":[{"_id":"303","name":"SPP 2111; TP: Ultrabreitbandiger Photonisch-Elektronischer Analog-Digital-Wandler (PACE) - Phase 2"}],"citation":{"bibtex":"@article{Zazzi_Müller_Weizel_Koch_Fang_Moscoso-Martir_Tabatabaei Mashayekh_Das_Drays_Merget_et al._2021, title={Optically Enabled ADCs and Application to Optical Communications}, volume={1}, DOI={<a href=\"https://doi.org/10.1109/ojsscs.2021.3110943\">10.1109/ojsscs.2021.3110943</a>}, journal={IEEE Open Journal of the Solid-State Circuits Society}, publisher={Institute of Electrical and Electronics Engineers (IEEE)}, author={Zazzi, Andrea and Müller, Juliana and Weizel, Maxim and Koch, Jonas and Fang, Dengyang and Moscoso-Martir, Alvaro and Tabatabaei Mashayekh, Ali and Das, Arka D. and Drays, Daniel and Merget, Florian and et al.}, year={2021}, pages={209–221} }","ama":"Zazzi A, Müller J, Weizel M, et al.
