Abstract
A frequency mixing apparatus with improved voltage gain and linearity is provided. The frequency mixing apparatus includes a transconductor, a separator, and a switching unit. A voltage gain of the transconductor is controllable, and the transconductor converts a Radio Frequency (RF) signal into a current signal under control of a self bias. The separator transfers the current signal to the switching unit. The switching unit outputs a signal having a frequency corresponding to one of a sum and a difference of a frequency of the RF signal and a frequency of a Local Oscillation (LO) signal by performing a switching operation according to the LO signal.
