A self-calibration technique for mismatches in image-reject receivers
This paper presents a modified image-reject Weaver architecture. The design automatically calibrates for phase and gain mismatches that limit the performance of image-reject receivers. On-line or off-line calibrations are possible without using any calibrating tone. An experimental CMOS prototype RF front-end operating at 1.8 GHz achieves an image rejection ratio of 59 dB using on-line calibration. The design was fabricated in a 0.35 /spl mu/m CMOS process and dissipates 160 mW from a 3 V supply during on-line calibration.
