Abstract

This paper presents design of the low power RF transceiver [1] which is suitable for wireless sensor network. Using 5.8GHz band has potentiality to achieve small size wireless sensor module because of smaller antenna in higher frequency. The proposed transceiver utilizes different modulation schemes for uplink and downlink to optimize power consumption and spectral efficiency. In addition, supply voltage of 0.5V can reduce the power consumption of overall RF transceiver. The prototype transceiver was fabricated in 65nm CMOS process, and the transmitter achieved EVM of 12.6% while consuming 2.86mW, and the receiver realizes sensitivity of -75dBm while consuming 0.83mW.
