Abstract
A frequency mixer circuit includes a gain stage and a mixer. The gain stage has a specific circuit design to convert a differential input voltage signal into a differential current signal with an input frequency. The mixer receives a differential local oscillator (LO) voltage signal with a LO frequency, and the differential current signal from the gain stage, and outputs a differential output voltage signal having a mixed frequency associated with the input frequency and the LO frequency.
