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

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

Frédéric Chastellain, Pierre-André Farine, Cyril Botteron

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 ...

Dual-frequency RF front-ends for GNSS receivers

Frédéric Chastellain

The Global Positioning System (GPS) is a trilateration system which allows to compute the position of a receiver from the time the signals need to propagate from the satellites down to the receiver. Since the Selective Availability (SA) was turned off in 2 ...
