868/915 MHz ZigBee receiver for personal medical assistance

This paper presents an architecture as well as circuit implementation of ZigBee receiver using 868/915 MHz band, which is compliant to the physical layer of IEEE standard 802.15.4. The post-layout simulation shows the packet error rate is less than 1% given SNR = 5 dB. The maximum power consumption is merely 183 /spl mu/W at 2.5 MHz.
