An 8-Bit 800 MS/s Loop-Unrolled SAR ADC With Common-Mode Adaptive Background Offset Calibration in 28 nm FDSOI

Yusuf Leblebici, Firat Çelik, Ayça Akkaya

This paper presents a low-power single-channel 8-bit loop-unrolled (LU) successive approximation register (SAR) analog-to-digital-converter (ADC) with a novel common-mode adaptive background comparator offset calibration scheme. LU-SAR ADCs use multiple co ...

A Maximum-Likelihood-based Multi-User LoRa Receiver Implemented in GNU Radio

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Orion Afisiadis, Joachim Tobias Tapparel, Mathieu Pierre Xhonneux

LoRa is a popular low-power wide-area network (LPWAN) technology that uses spread-spectrum to achieve long-range connectivity and resilience to noise and interference. For energy efficiency reasons, LoRa adopts a pure ALOHA access scheme, which leads to re ...

Frequency division using a soliton-injected semiconductor gain-switched frequency comb

Tobias Kippenberg, Junqiu Liu, Wenle Weng

With optical spectral marks equally spaced by a frequency in the microwave or the radio frequency domain, optical frequency combs have been used not only to synthesize optical frequencies from microwave references but also to generate ultralow-noise microw ...

Frequency Division Using a Soliton-Injected Semiconductor Gain-Switched Frequency Comb

Tobias Kippenberg, Junqiu Liu, Wenle Weng

By injecting a soliton microcomb into a semiconductor laser that is driven by a sinusoidal current at the subharmonic frequencies of the soliton rate, we demonstrate broadband gain-switched frequency comb generation and low-noise microwave synthesis. (C) 2 ...

Simulation of Instability in Time-Sensitive Networks with Regulators and Imperfect Clocks

Guillermo Aguirre Rodrigo

Regulators are used in time-sensitive networks in order to reshape traffic reducing the burstiness generated by the aggregation systems within the network. Regulators, in terms of the IEEE TSN group are defined as Asynchronous Traffic Shaping or what in th ...

Network coded multipath and related techniques

Emre Telatar, Arno Schneuwly, Derya Malak

Techniques are disclosed for adaptive coding and scheduling of packets in wireless networks. The adaptive coding and scheduling can be achieved by utilizing a discrete water filling (DWF) scheme. In an example, a computer-implemented method to adaptively c ...

Progress and pitfalls of using isobaric mass tags for proteome profiling

Loïc Dayon

Introduction: Quantitative proteomics using mass spectrometry is performed via label-free or label-based approaches. Labeling strategies rely on the incorporation of stable heavy isotopes by metabolic, enzymatic, or chemical routes. Isobaric labeling uses ...

Training Channel Selection for Learning-based 1-bit Precoding in Massive MU-MIMO

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Sitian Li

Learning-based algorithms have gained great popularity in communications since they often outperform even carefully engineered solutions by learning from training samples. In this paper, we show that the selection of appropriate training examples can be im ...

Ultralow-noise photonic microwave synthesis using a soliton microcomb-based transfer oscillator

Tobias Kippenberg, Erwan Guillaume Albert Lucas

The synthesis of ultralow-noise microwaves is of both scientific and technological relevance for timing, metrology, communications and radio-astronomy. Today, the lowest reported phase noise signals are obtained via optical frequency-division using mode-lo ...
