This electronics video tutorial provides a basic introduction into varactor diodes also known as varicaps which can behave as voltage controlled capacitors. The junction capacitance of the diode is inversely related to the reverse voltage applied to it. Varactor diodes are very useful in tuned circuits and voltage controlled oscillator circuits.
