A CMOS ultra-wideband impulse generator for 22–29 GHz automotive radar application

Abstract

This paper presents the design and simulation of a CMOS ultra-wideband pulse generator using IBM 90nm CMOS technology. The operating frequency band of the pulse generator is from 22 to 29 GHz for the application of short-range automotive radar. The pulse generator has a simple architecture using digital circuits. The simulation results show that the power spectral density of the pulse generator has a center frequency of 24.4 GHz and has a -10 dB bandwidth from 22 to 29 GHz.
