Any PN junction diode can be used as a variable capacitor in reverse biased mode, as well as in the forward biased mode before the knee voltage. The capacitance is usually very small as the junction ...

Abstract: This paper introduces a novel variable capacitor module (VCM) for a wireless power transfer (WPT) systems system. It operates based on the principle that ceramic capacitance changes with the ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...
