A tunable OOK IR-UWB pulse generator in 0.18 µm technology

A new energy-efficient, tunable impulse radio ultra-wideband (IR-UWB) pulse generator is investigated in the paper. The low complexity architecture is composed of a data and clock synchronization block, a glitch generator, an impulses combiner, and a pulse shaping filter. It is designed and simulated in low-cost 0.18 μm UMC CMOS technology. The simulation results showed spectrum that covers whole UWB band and fully complies with the corresponding FCC spectral mask. The pulse duration is around 0.8 ns, and the peak-to-peak amplitude is 488 mV on 50 O output load. It has low power consumption of 1.1 mW corresponding to energy consumption of 11 pJ per pulse for 100 MHz pulse repetition frequency (PRF).
