Abstract
A frequency conversion apparatus for converting an input signal having an input frequency into an output signal having an output frequency. The frequency conversion apparatus includes a first multiplier and a gm stage. The first multiplier multiplies a first local signal having a first frequency with a second local signal having a second frequency to generate a differential current signal having a third frequency. The third frequency is substantially the same as the input frequency or the output frequency, and the first frequency and the second frequency are different from the input frequency or the output frequency. The gm stage is electrically connected to the first multiplier and receives the differential current signal and the input signal to generate the output signal.
