A 12-mW 500-Mb/s 1.8-μm CMOS pulsed UWB transceiver suitable for sub-meter short-range wireless communication

Abstract

This paper describes a 500-Mb/s 12-mW pulsed UWB transceiver in 1.8-mum CMOS technology for sub-meter short-range wireless communication. The transceiver employs two functional blocks for reducing power dissipation: one is an on-chip transformer-based DC-RF pulse power converter and another is an asynchronous RF-baseband direct demodulator. The prototype chip with printed dipole antenna can operate at a bit-error rate of 10-3 or less on 40-cm distance, while dissipating less than 24 muW/Mb/s.
