Abstract :
An all-digital CMOS ultra-wideband (UWB) pulse generator with 3-5GHz frequency range is presented in this paper. The pulse generator is tunable in both amplitude and bandwidth to meet the FCC spectral mask requirement. The circuit is implemented in 0.13 μm CMOS process with a core area of 0.024 mm2 and achieving an energy efficiency of 2.5 pJ/pulse at 200M pulse/s.
