Cross-layer investigation of continuous-time sigma–delta modulator under aging effects

Autor: You Wang, Kaikai Liu, Herve Petit, Hao Cai, Jean-François Naviner, Lirida Alves de Barros Naviner

Publikováno v: Microelectronics Reliability. 55:645-653

In order to achieve reliability study in large and complex analog and mixed signal (AMS) circuits and systems, it is required to develop effective reliability-aware design methodologies and exploration tools. This paper discusses two aging mechanisms

Journal of Astronomical Instrumentation, 2016, 5 (4), pp.1641020. ⟨10.1142/S2251171716410208⟩

The design of a new digital radio receiver for radio astronomical observations in outer space is challenged with energy and bandwidth constraints. This paper proposes a new solution to reduce the number of samples acquired under the Shannon–Nyquist

In order to reduce power consumption and limit the amount of data acquired and stored for astrophysical signals, an emerging sampling paradigm called compressed sensing (also known as compressive sensing, compressive sampling, CS) could potentially b

IEEE MTT-S International Microwave Symposium (IMS), May 2016, San Francisco, United States. ⟨10.1109/MWSYM.2016.7540033⟩

Distorsion and attenuation occuring during track and hold transition are challenging for Track-and-hold amplifier (THA) with bandwidth larger than 10GHz. Moreover, single-ended to differential conversion is mainly required for radar applications. A s

Reliability aware design of low power continuous-time sigma–delta modulator

Autor: Herve Petit, Jean-François Naviner, Hao Cai

Publikováno v: Microelectronics Reliability. 51:1449-1453

Circuit reliability has become a major bottleneck due to ageing degradation. In this paper, reliability-aware methodology and ageing analysis of low power sigma–delta (ΣΔ) modulator are presented. HCI and NBTI are considered as the dominating age

Adaptive and digital blind calibration of transfer function mismatch in time-interleaved ADCs

Autor: Herve Petit, Patrick Loumeau, Gael Kamdem De Teyou

Publikováno v: NEWCAS

In this paper we propose a digital blind calibration scheme for Time-Interleaved ADCs based on transfer function mismatch which corrects gain, time-skew and bandwidth mismatch errors. The estimation of mismatches uses an adaptive filtering structure

Statistical analysis of noise in broadband and high resolution ADCs

Autor: Stephane Paquelet, Gael Kamdem De Teyou, Patrick Loumeau, Hussein Fakhoury, Herve Petit, Yann Le Guillou

Publikováno v: ICECS

The estimation of mismatch-induced errors between the channels of a Time-Interleaved ADC is crucial for implementing an efficient calibration method. This step is often done with the assumption that all the noise sources have a white gaussian distrib
