Abstract :
In this paper, the design and simulation of a CMOS ultra-wideband pulse generator using TSMC 0.18 mum CMOS technology is presented. The operating frequency band of the pulse generator is from 3 to 10 GHz for the application of ultra-wideband (UWB) communications. The structure of the impulse generator is based on the current-steering digital-to-analog converter (DAC). The impulse generator has the feature of high-tunability and the simulation results show that the output of the impulse generator complies with the FCC regulations and has a power consumption of 27 mW at a 50 MHz pulse repetition rate (PRR).
