ZigBee 868/915-MHz Modulator/Demodulator for Wireless Personal Area Network

Abstract

This paper presents an architecture as well as circuit implementation of a ZigBee modulator/demodulator in the transceiver for personal area network, which is compliant with the physical layer of IEEE standard 802.15.4. A test prototype has been designed and fabricated using 0.18-mum single-poly six-metal 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 measurement results show that packet error rate (PER) is less than 1% given SNR = 5 dB. The total power consumption is merely 251 muW at a 2.4-MHz system clock.
