A Versatile 1.4-mW 6-bits CMOS ADC for Pulse-Based UWB Communication Systems

Pierre-André Farine, Cyril Botteron, Christian Robert, Frédéric Chastellain, Saeed Ghamari

An Analog to Digital Converter (ADC) using the low duty-cycle nature of pulse-based Ultra Wide-Band (UWB) communications to reduce its power consumption is proposed. Implemented in CMOS 180 nm technology, it can capture a 5 ns window at 4 GS/s each 100 ns, ...

Looking Inside Modern Receivers

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain

The principle of wireless communications originates from the need to communicate between two points separated by a distance sufficiently large to prevent the use of wires. This article talks about modern receivers in which the basic building blocks of mode ...

A Galileo E1b,c RF front-end for Search-and-Rescue applications

Pierre-André Farine, Cyril Botteron, Frédéric Chastellain, Marcel Baracchi Frei, Davide Manetti

The current Search-and-Rescue (SAR) service, which is based on the Cospas-Sarsat system, suffers from major limitations such as poor position accuracy, long alert times and high false alarm rate. Two types of distress signals are used, the 121.5MHz/(up to ...
