New 0.18-mu m CMOS pulse generator for impulse radio ultra-wideband communication systems

Abstract

This article presents a new circuit to generate a higher-order derivative Gaussian pulse for the impulse radio ultra-wideband (IR-UWB) communication systems. This IR-UWB pulse generator is designed and measured with the TSMC 0. 18- mu m CMOS process. The circuit is able to generate a symmetrical and low-ringing pulse in a frequency band from 3.1 to 10.6 GHz. Our work shows that the pulse generator's output pulse width is 500 ps with an amplitude of 40 in V (peak to peak). The measurement results validate our design and the circuit functionality.
