Abstract

A varactor includes a field effect transistor (FET) integrated with at least a portion of a bipolar junction transistor (BJT), in which a back gate of the FET shares an electrical connection with a base of the BJT, and in which a reverse voltage applied to the back gate of the FET creates a continuously variable capacitance in a channel of the FET.
