摘　　要：In this paper, a 780MHz low-power fully integrated receiver front-end fabricated in 0.18μm CMOS process is presented. A low noise amplifier utilizing current-reused configuration and single-balance passive mixer are proposed to achieve high conversion gain, low noise figure and low power consumption for wireless sensor network. As the measurement results show, the proposed front-end gets a conversion gain of 27dB a noise figure of 5.TdB, an IIP3 of--20dBm and an IIP2 of 5dBm with only 1.71mA current from an 1.8V power supply.
