Asynchronous sar adc with unit length capacitors and constant common mode monotonic switching
A Successive Approximation Register Analog-to-Digital Converter (SAR ADC) comprising a Track-and-Hold (T/H) switch configured for a sampling of an input voltage in the form of charge onto a capacitor; a Capacitive Digital-to- Analog Converter (CD AC) opera ...
2021Low Noise Clock Generation: Modeling, Analysis and Implementation
The aim of this thesis is to implement, analyze and improve the selected low noise clock
generation and distribution techniques for ADC implementations. The thesis is divided into
two parts. The first part focuses on the sampling phase generation and distr ...
EPFL2021Uncertain Sampling with Certain Priors
Sampling has always been at the heart of signal processing providing a bridge between the analogue world and discrete representations of it, as our ability to process data in continuous space is quite limited. Furthermore, sampling plays a key part in unde ...
EPFL2021Real-time feedback control system for ADITYA-U horizontal plasma position stabilisation
Harshita Raj, Rohit Kumar, Shivam Gupta
The ADITYA-U tokamak (R-0 = 0.75 m, a = 0.25 m) is designed to shape plasma column in both single and double null diverter configurations. It is quite well known that sustaining a shaped plasma in tokamak requires very good plasma column position control, ...
2021Watermarking-based Defense against Adversarial Attacks on Deep Neural Networks
James Richard Larus, Xiaoting Li, Dinghao Wu, Junjun Zhang
The vulnerability of deep neural networks to adversarial attacks has posed significant threats to real-world applications, especially security-critical ones. Given a well-trained model, slight modifications to the input samples can cause drastic changes in ...
IEEE2021Optimization of a Py-GC/MS method for silicone -based lubricants analysis
Christophe Roussel, Céline Burnier
Condom evidence can be analysed using several analytical techniques, such as FTIR, MALDI-MS or DART-TOF-MS, but the only one that was used on real samples for transfer and persistence studies in the context of sexual assault or rape cases was Py-GC/MS. How ...
2020On the optimal sampling design for the Graph Total Variation decoder: recovering piecewise-constant graph signals from a few vertex measurements
Rodrigo Cerqueira Gonzalez Pena
Compressed Sensing teaches us that measurements can be traded for offline computation if the signal being sensed has a simple enough representation. Proper decoders can exactly recover the high-dimensional signal of interest from a lower-dimensional vector ...
EPFL2020Lower Bounds on Active Learning for Graphical Model Selection
Volkan Cevher, Jonathan Mark Scarlett
We consider the problem of estimating the underlying graph associated with a Markov random field, with the added twist that the decoding algorithm can iteratively choose which subsets of nodes to sample based on the previous samples, resulting in an active ...
2017A Maximum-Likelihood Sequence Detection Powered ADC-Based Serial Link
A 0.88 mm 2 65-nm analog-to-digital converter (ADC)-based serial link transceiver is designed with a maximum-likelihood sequence detector (MLSD) for robust equalization. The MLSD is optimized in a pipelined look-ahead architecture to reach 10 Gb/s at 5.8 p ...
IEEE201727.3 Area-efficient 1GS/s 6b SAR ADC with charge-injection-cell-based DAC
To support growing data bandwidths, high-speed moderate-resolution ADCs have become vital for high-speed serial links. Interleaved SAR ADCs achieve high sampling speeds and good energy efficiency. However a challenge is that these ADCs are large and theref ...
