Abstract

A new fully digital CMOS pulse generator for impulse radio ultra-wideband (UWB) systems is presented. First, the shape of the pulse which best fits the FCC regulation in the 3.1–5 GHz sub-band of the entire 3.1–10.6 GHz UWB bandwidth is derived and approximated using rectangular digital pulses. In particular, the number and the width of pulses that approximate an ideal template are found through an ad hoc optimization methodology. Then a fully differential digital CMOS circuit that synthesizes the pulse sequence is conceived and its functionality demonstrated through post-layout simulations. The results show a very good agreement with the FCC requirements and a low power consumption.
