Definition of varactor in English:

varactor

noun vəˈraktəˌvəˈraktər

A semiconductor diode with a capacitance dependent on the applied voltage.
Example sentencesExamples
- This paper presents a performance evaluation and comparison of three different types of CMOS varactors based on measurements.
- This nonlinearity allows the varactor to be used also as a harmonic generator.
