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 first and second differential oscillatory voltage signal pairs upon a differential input voltage signal pair to generate first and second differential mixed current signal pairs. The load module includes two RL circuits and a negative resistance providing circuit that cooperate to convert the first and second differential mixed current signal pairs into first and second differential mixed voltage signal pairs. Each RL circuit includes two variable resistors, and an inductor connected between the variable resistors.
