Switch with envelope injection

Abstract:

Aspects of this disclosure relate to a switching circuit with enhanced linearity. The switching circuit can include a switch and an envelope generator. The switch can receive an input signal, provide an output signal, and receive an envelope signal corresponding to an envelope of the input signal. The envelope generator can generate the envelope signal so as to cause intermodulation distortion in the output signal to be reduced to cause linearity of the switch to be improved.
