A compact low power ultra wideband impulse generator on 0.18 μM CMOS technology

Abstract

This article presents a compact ultra wideband (UWB) impulse generator (IG) with special shaping circuit that can operate intermittently.The pulse last for 4 ns and the measured −10 dB bandwidth is about 460 MHz. The UWB IG employs biphase shift keying (BPSK) scrambling and the power consumption is 7.3 mW at a repetition frequency of 125 Mbps. It was fabricated using Taiwan Semi-conductor Manufacture Company (TSMC) 0.18 μm CMOS process. © 2011 Wiley Periodicals, Inc.
