A fully digital Ultra-wide band sub-GHz pulse generator

The design of a fully digital tunable sub-GHz Ultra-wide band (UWB) pulse generator is presented. The pulse generator has been implemented in a 0.13μm CMOS technology. Post-layout simulation shows that the proposed pulse generator achieves UWB pulses with a 900mVpp magnitude while consuming 27pJ by pulse under 1.2V supply voltage. The tuning capabilities allow the center frequency setting between 400MHz and 610MHz.
