摘　　要：This paper presents a 2.4 GHz CMOS transceiver for the wireless personal area network （WPAN） inte- grated in 0.18/zm CMOS technology. This transceiver adopts a low-IF receiver, a MUX based transmitter and a fast-setting fractional-N frequency synthesizer. For achieving low cost and low power consumption, an inductor- less receiver front-end, an adaptive analog baseband, a low power MUX and a current-reused phase-locked loop （PLL） have been proposed in this work. Measured results show that the receiver achieves-8 dBrn of lIP3 and 31 dB of image rejection. The transmitter delivers 0 dBm output power at a data rate of 2 Mbps. The current consumption is 7.2 mA in the receiving mode and 6.9 mA in the transmitting mode, respectively.This paper presents a 2.4 GHz CMOS transceiver for the wireless personal area network （WPAN） inte- grated in 0.18/zm CMOS technology.
