A reconfigurable, 0.13µm CMOS 110pJ/pulse, fully integrated IR-UWB receiver for communication and sub-cm ranging

Abstract

Impulse radio ultra-wideband (IR-UWB) proved to be a strong candidate for energy-efficient communication and ranging, resulting in multiple low-energy IR-UWB implementations. Current state-of the art publications however only realize parts of a complete IR-UWB RX system, lacking either a digital back-end (DBE), an analog front-end (AFE) and/or algorithms for synchronization and ranging. A 110 pJ/pulse, single-chip IR-UWB receiver for operation in the 0 to 960 MHz band is presented in 0.13 mum CMOS.Wireless communication was demonstrated with a radio range in excess of 10 m, the furthest published for similar radios.
