Abstract
A down-conversion mixer includes a converting-and-mixing circuit and a load circuit. The converting-and-mixing circuit 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 circuit includes two transistors each having a transconductance that varies according to a control voltage, two resistors each decreasing a threshold voltage of a respective one of the transistors, and a resistor-inductor circuit cooperating with the transistors to convert the differential mixed current signal pair into a differential mixed voltage signal pair.
