Abstract

A programmable varactor apparatus may include multiple binary weighted varactors controlled by multiple digital varactor bits. A programmable varactor apparatus may include a plurality of binary weighted varactors, and a control to selectively disable one or more of the plurality of binary weighted varactors to decrease an effective capacitance of the programmable varactor apparatus. A method for changing an effective capacitance of a programmable varactor apparatus may include providing a plurality of binary weighted varactors, and disabling one or more of the plurality of binary weighted varactors to decrease the effective capacitance of the programmable varactor apparatus.
