JCIR_V2_N4_RP5 Tunga Mounika Bharathi Muni Journal on Circuits And Systems 2322–035X 2 4 29 32 VLSI (Very Large Scale Integration), HSPICE (Hewlett Simulation Program with Integrated Circuit Emphasis), CMOS (Complementary Metal Oxide Semiconductor), Microwave radar, Pulse generator, Subthreshold Adiabatic Logic Microwave radar requires the development of pulse generators that are capable of producing a succession of pulses in very short time durations. The generation of radar transmitter requires high-power and high-voltage pulses, whereas the indicator and ranging circuits require pulses of negligible power and relatively low voltage. This paper presents a pulse generator which is designed by using edge generator circuit with edge tuning capability. The pulse generator circuit obtained generates the pulses dissipating power which is less when compared to CMOS (Complementary Metal Oxide Semiconductor) logic. It is an energy efficient circuit which can be implemented in HSPICE using 0.18μm CMOS standard process technology. September - November 2014 Copyright © 2014 i-manager publications.
