摘要
This paper presents a low power RF transceiver for 2.4 GHz ZigBee applications. The current reused inductor-less-load balun low noise amplifier (LNA) with quadrature mixer is proposed for area and power saving for low-IF receiver. The transmitter adopts power efficient power ampli fier (PA) to improve transmitting efficiency. This RF transceiver is implemented in 0.18 mu m CMOS technology. The receiver achieves 6.5 dB noise figure (NF) and 20 dB conversion gain. The transmitter delivers maximum +3dBm output power with PA efficiency of 30%. The receiver and transmitter front-end dissipate 1.9 mW and 5.3 mW at 1.8 V supply, respectively. The whole die area is 0.95 mm(2).
