Abstract

A novel DC-to-960MHz impulse radio ultra-wideband (IR-UWB) transceiver based on threshold detection technique is developed. It features a digital pulse-shaping transmitter, a DC power-free pulse discriminator and an error-recovery phase-frequency detector. The developed transceiver in 90nm CMOS achieves the lowest energy consumption of 2.2pJ/bit transmitter and 1.9pJ/bit receiver at 100Mbps in the UWB transceivers.
