A CMOS variable width short-pulse generator circuit for UWB RADAR applications

This paper describes a variable width short pulse generator circuit for UWB radar applications, designed in a 0.18μm CMOS technology. This circuit is capable of generating pulses with a duration from 0.7 ns to 3.5 ns and an amplitude of 0.7 V with a 50 Ω load. The power supply voltage can be as low as 1.5 V and uses only 2.3 mA of power supply current.
