Here are a number of alternative ways to avoid problems when driving Varactor Diodes. Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a ...

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.

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 than the intrinsic stuff to make ...

circuits. 2. BSIM (Berkeley Short-channel IGFET Model) is the conventional model generally utilized in simulating MOS-Varactor. It was developed by the University of California, Berkeley.
