Beschreibung:
<jats:p> In this paper, we present, at transistor level, a very low complexity Gaussian monocycle pulse generator/modulator for DPSK low voltage and low power tunable ultra-wideband (UWB) applications. The pulse generator, simulated in a SMIC 0.13 μm CMOS technology, provides a tunable, both in pulse width duration and repetition time, Gaussian monocycle compliant with the sub-GHz ETSI band and suitable to be used in UWB radio applications. The preliminary IC simulation results show a pulse duration from 1 ns up to 20 ns with good pulse symmetry and with the DPSK modulation capability. The circuit power consumption is about 1 mW from a 1.8 V power supply. </jats:p>
