Fully tunable UWB pulse generator with zero DC power consumption

The design of a fully tunable pulse generator using only logic cells is presented and simulated with 0.13 mum standard CMOS process. The generator is based on the elementary pulse combination and can synthesize different UWB pulse shapes. The generator uses logic gates to achieve the elementary pulses and a H-bridge to make the combination which leads to a zero DC power consumption. To achieve FCC compliant pulse having 2 V_PP magnitude the generator consumes 140 pJ by pulse using 1.2 V supply voltage.
