A 15pJ/pulse all-digital UWB pulse generator with pulse tuning capability

Abstract

A novel all-digital ultra-wideband pulse generator (PG) with pulse tuning capability has been implemented in a standard 0.18 CMOS process with ultra low dynamic energy consumption of 15pJ per pulse with no static current flow at 200MHz pulse repetition frequency (PRF) and 1.8V power supply. The PG generates bi-phase Gaussian, plus its 1 st and 5 th derivatives with a tunable pulse width, amplitude and transmit (Tx) power, using a simple circuitry, through a precise timing control of H-bridge output stage. All-digital architecture allows easy integration into a standard CMOS process.
