The paper presents a low power CMOS pulse generator design for impulse based UWB applications. The basic structure of the design involves a variable length rectangle pulse generator, a CMOS quasi-Gaussian pulse shaping filter and a small monopole antenna model. Simulation results show the pulse after the antenna is compliant with the FCC's spectrum mask for 0~960 MHz band and has a power consumption of 234 muW at the pulse repetition frequency of 100 MHz. The CMOS circuit used to create the pulse generator is simple and lends itself to a low-power, single-chip UWB transmitter solution
