A 2.8–7.5 pJ/pulse highly-flexible impulse-radio ultra-wideband pulse-generator

Abstract

A low-power on-off-keying impulse-radio (IR) ultra-wideband (UWB) pulse generator (PG) intended for wireless-powered IR-UWB radio applications is presented. The proposed PG has high flexibility, the center frequency, output power and pulse-width (PW) are controllable depending on channel conditions and data rates. Qualitative frequency-domain and transient analyses are presented. A new figure-of-merit (FoM) is proposed such that a more precise comparison between different PGs can be made. The PG is successfully implemented in a TSMC 90 nm CMOS process, measurements show the energy consumption and FoM to be 2.8–7.5 pJ/pulse and 1.6–2.6% respectively. The output swing and PW are 277–329 mVp-p and 509–1088 ps respectively. The core area is 0.092 mm².
