Description
Summary:A low-power full-band 802.11abg transceiver in 0.15mum 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 140degC operation temperature is achieved by sensing technique. On-chip power detector and transmitter to receiver feedback loop estimate 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 receives modes and 200/107mA for 2.4/5GHz transmits modes respectively. The low power consumption, high integration and robustness make this transceiver suitable for portable applications
