Abstract
A down-conversion mixer includes a converting-and-mixing module and a load module. The converting-and-mixing module performs voltage-to-current conversion and mixing with a differential oscillatory voltage signal pair upon a differential input voltage signal pair to generate a differential mixed current signal pair. The load module includes a first transistor, a second transistor and a resistor-inductor (RL) circuit that cooperatively convert the differential mixed current signal pair into a differential mixed voltage signal pair. Each of the first and second transistors has a transconductance that varies according to a control voltage.
