A Low-Power 2.45 GHz ZigBee Transceiver for Wearable Personal Medical Devices in WPAN

Abstract

This paper presents the architecture as well as the circuit implementation of a ZigBee transceiver using 2.45 GHz band, which is compliant with the physical layer of IEEE 802.15.4 standard. A prototypical system and chip has been designed using 0.18-mum CMOS process with core area of 0.16 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . The simulation results shows the packet error rate is less than 1% given E <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">b</sub> /N <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> = 9 dB. The total power consumption is merely 271 muW at a 8.0 MHz system clock.
