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 muCMOS process with ultra low dynamic energy consumption of 15 pJ per pulse with no static current flow at 200 MHz pulse repetition frequency (PRF) and 1.8 V power supply. The PG generates bi-phase Gaussian, plus its 1st and 5th 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.
