I googled "define parametric amplifier" and got this.

Definition of parametric amplifier. : a high-frequency amplifier whose operation is based on time variations in a parameter (such as reactance) and which converts the energy at the frequency of an alternating current into energy at the input signal frequency in such a way as to amplify the signal.

Didn't you do that before posting your question?
