摘要：

A low-power full-band 802.11abg transceiver in 0.15 mu m CMOS technology is presented. It shows 4.4/4dB low noise figures in 2.4/5GHz receiver chains. An on-chip PA (power amplifier) delivers 20dBm Output P-1dB- -40 to 140 degrees C operation temperature is achieved by sensing technique. Onchip power detector and transmitter to receiver feedback loop estimate the I/Q imbalance, and a new I/Q compensation scheme is implemented in LO (local oscillator) rather than signal paths. It consumes 65/75mA for 2.4/5GHz receive modes and 200/107mA for 2.4/5GHz transmit modes respectively. The low power consumption, high integration and robustness make this transceiver suitable for portable applications.
