A 264-µW 802.15.4a-Compliant IR-UWB Transmitter in 22nm FinFET for Wireless Sensor Network Application

A fully-integrated 802.15.4a-compliant IR-UWB transmitter (TX) in Intel 22nm FinFET Low Power process is presented. The TX consumes 264μW while transmitting -16.2dBm at 110kbps data rate in 8GHz band with 9.1% TX efficiency. The TX supports both coherent and non-coherent 802.15.4a operation and only requires a 32.768kHz real-time clock for non-coherent operation.
