A 4GHz CMOS 130 nm IR-UWB dual front-end transceiver for IEEE802.15 standards

A single chip CMOS 130 nm transceiver for UWB-IR communications was assembled and measured for further integration into a demonstrator aiming compatibility with the recently published IEEE802.15.6 standard for Body Area Networks. The transmitter achieves a 10.9 mA current consumption for the 15.6MHz pulse repetition frequency and 1.5V peak-to-peak voltage. The receiver is an innovative combination of a low current consumption non coherent envelop detector and of a high sensitivity coherent quadrature demodulator. Different compromises in sensitivity, current consumption and acquisition speed are made possible. This paper briefly describes the architecture and provides the chip measurement results.
