Abstract
A 1 GHz image-rejection down-converter implemented in 0.8 mu m CMOS pr ocess is presented. The down-converter consists of a quadrature genera tor and mixers. The proposed architecture has the characteristic of im age-rejection insensitive to phase error of the higher frequency first local oscillator(LO). The down-converter has image-rejection characte ristic of 29.3dB under 2 degrees phase error of the lower frequency se cond LO, The down-converter dissipates 108mW at 3.3V supply.
