Variable capacitance diodes are produced and characterized for use as electronically-variable capacitors, and are widely used in tuning and frequency synthesis applications. While most all diodes exhibit a junction capacitance that decreases as the amount of reverse bias voltage applied increases and are capable of functioning as variable capacitance diodes, products specifically marketed as such are produced and characterized with this use in mind.
