Non-Linear Capacitance Based Parametric Mixer

摘要

A method and apparatus for frequency conversion. The apparatus includes a mixer configured to provide an output signal with a converted frequency, a local oscillator, and a non-linear transmission structure operably connected to the mixer and the local oscillator. The non-linear transmission structure is configured to cancel at least a portion of non-linearity of the mixer from the output signal and to modify a gain of the output signal. The local oscillator may provide a local oscillator signal to the non-linear transmission structure. The non-linear transmission structure may also be configured to modify the local oscillator signal to cancel at least the portion of the non-linearity of the mixer and to modify the gain of the output signal, and provide the modified local oscillator signal to the mixer.
