The transconductance/amplification stage has a current-reuse CMOS topology wherein an input frequency signal is converted into a frequency current, low-frequency components are removed from said frequency current by means of the high-pass filter network, said frequency current is fed into the mixing stage, modulation occurs in the mixing stage, and then an intermediate-frequency signal is generated and output. Once high-frequency components are removed from the intermediate-frequency signal by means of the low-pass filter network, the intermediate-frequency signal is sent again for input into the transconductance/amplification stage, then amplified in the transconductance/amplification stage and output. The mixer transconductance/amplification stage employs a current-reuse technique. The input frequency and the output intermediate-frequency ...
