This paper presents architecture as well as the circuit implementation of a ZigBee transceiver using 868/915 MHz band, which is compliant to the physical layer of IEEE 802.15.4. Two low-power analog-to-digital converters (ADC) are integrated within the proposed transceiver. The ADC is a 5-bit SA-based (successive approximation) structure. The post-layout simulation shows the packet error rate (PER) is less than 1% given SNR = 5 dB. The overall power consumption is merely 6.57 mW (Tx power = 3.28 mW, Rx power= 3.29 mW)
