Abstract:
A frequency mixer circuit includes a mixer, a load stage, and again stage. The load stage cooperates with the mixer to generate a differential output voltage signal with a mixed frequency according to a differential local oscillator voltage signal and a differential input voltage signal. The gain stage has a transconductance, and a magnitude of the differential current signal and the transconductance have a positive relationship therebetween, so as to result in a positive relationship between the transconductance and a conversion gain which is a ratio of magnitude of the differential output voltage signal to magnitude of the differential input voltage signal.
