The Nuts and Bolts of Tuning Varactors
Abstract: construction of varactor diode varactor diode model in ADS pn junction diode
Text: The Nuts and Bolts of Tuning Varactors Introduction Many electronic systems must be tuned through the variation of reactance of one or more circuit elements. In these applications it is often desirable to perform this tuning under electronic rather than manual control. Tuning varactor diodes, which are pn junction devices that act as voltagecontrolled variable capacitors, can perform this function.
