étude d'éléments de base et de concepts pour un numériseur à très large bande passante et à haute résolution

Abstract : Nowadays, high bandwidth signals can be sampled at even higher sampling frequencies. Signals from telecommunication systems, experimental sensors or radar systems can be directly digitized, without analog IF conversion. This work is about the design of a sampling system for radar applications, which need a significant increase of actual systems resolution. The main objectives we target are a sampling frequency of 40 GS/s, a bandwidth of15 GH and 10 effective bits at 8 GHz. As very promising results have been obtained with single-shot sampling architectures, this study is based on this principle which has been adapted to large sampling windows. We have chosen an InP HBT technology because it has the best potentialities for our application. Within these systems, two basic elements have been optimized to increase the resolution: the inverter in order to reduce the jitter, and the track-and-hold, to increase the linearity. Taking the results into account, three innovative sampling architectures have been proposed. For each one of them, a system was designed and its performances were simulated.
