Single-chip CMOS pulse generator for UWB systems

Abstract

This paper describes the integration in a CMOS 130 nm technology of an ultra wide band (UWB) pulse generator. The implemented generator controls the output pulse shape, and thus the corresponding spectrum. Furthermore, the pulse generator supports both position modulation (2-PPM) and polarity modulation (BPSK) and draws 5 mA from 1.2 V. Spectral and temporal laboratory measurements of the single-chip pulse generator are presented.
