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 ...

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.

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 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.

Toshiba Corporation (TOKYO: 6502) today announced the development of a compact MOS-Varactor 1 simulation model that delivers high level accuracy from DC to the millimeter wave (60 GHz) region. The ...
