exploit the voltage-dependent capacitance of a reverse-biased p–n junction. Varactors are used as voltage-controlled capacitors. They are commonly used in voltage-controlled

switched capacitors and varactors. The components discussed in this article are based on RF MEMS switches, switched capacitors and varactors. These components
