Abstract :
A fully integrated power-efficient CMOS pulsed ultra-wideband (I-UWB) transmitter for biomedical applications operating in the 3 - 5 GHz band is implemented in a 65 nm CMOS technology. The UWB transmitter adopts a low-complexity ring oscillator-based pulse generator architecture and pulse-position-modulation (PPM) for increased power efficiency and minimal silicon area. The transmitter consumes zero static bias power and achieves an energy efficiency of 19 pJ/pulse at 200 MHz pulse repetition frequency (PRF) while occupying 68 × 68 μm2 of silicon area.
