Varactor (varicap) circuit symbol. How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron ...

LC-tank circuit portion. Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage.

This revealed that the V47 diodes were not the dual Vishay diode, but rather the American MicroSemiconductor varactor diode. The varactor-input amplifier was invented by Bob Pease’s boss George ...

Varactor Diodes Varactor diodes are p-n junctions that change capacitance and series resistance with applied bias. This change in capacitance is utilized to tune the tank circuit of VCO for required ...

In a real circuit, the parameter often is capacitance — although it doesn’t have to be — but instead of using a mechanically variable capacitor, a varactor provides the varying capacitance.

In fact, this quality is exploited in varactor diodes, ... The main circuit is powered by your 13.8 V bench supply, but part of the circuit needs 9 V.
