Description
Summary:A new low-complexity energy-efficient impulse radio ultra-wideband (IR-UWB) pulse generator is investigated in the paper. It is designed and simulated in low-cost 0.13 μm UMC CMOS technology. The spectrum adjustable architecture consists of a tunable glitch generator, a BPSK modulator, two voltage controlled ring oscillators, an output buffer and a shaping filter. The simulation results showed spectrum that covers the higher UWB band and fully complies with the corresponding FCC spectral mask. The pulse duration is around 0.6 ns, and the peak-to-peak amplitude is 380 mV on 50 Ω output load. It has low power consumption of 0.44 mW corresponding to energy consumption of 2.2 pJ per pulse for 200 MHz pulse repetition frequency (PRF).
