Electronically tunable capacitor

摘要: A tunable capacitor (10) includes a first (12) formed from semiconductor material and having terminal (24) defining an anode, second (14) integrally with the material, being operatively coupled in series capacitor, (36) cathode. The is as field effect device or MOSFET configured to provide depletion region controlled by applying control voltage (42) of device. reverse biased application bias between anode cathode predetermined capacitance while applied varies such that varied independently voltage.
