Related to Varicap: Varactor diode


 (və-răk′tər, vă-)
A semiconductor device in which the capacitance is sensitive to the applied voltage at the boundary of the semiconductor material and an insulator.

[var(iable) + (re)act(ance) + -or.]


(Electronics) a semiconductor diode that acts as a voltage-dependent capacitor, being operated with a reverse bias. Compare varistor

BOSTON -- In a recent evaluation of RF MEMs technology, the Strategic Technologies Practice at Strategy Analytics has recognized WiSpry's MEMs varicap (variable capacitor) as a practical device that could reduce handset bills of material.
Additional process modules allow X-FAB customers to implement depletion NMOS, natural PMOS, varicap diodes with increased CV-behavior, photodiodes with improved uniformity and n-channel JFET.
In addition, the chip cuts the external component count, and therefore cost, by eschewing IF (Intermediate Frequency) filters, ceramic capacitors, and varicaps.
While MEMS accelerometers are expected to follow the same evolution, few other MEMS products (micro autofocus, micro zoom, gyroscopes, varicaps, O) are at the emerging stage.
