Diodes – Variable Capacitance (453) – Page 2

Variable capacitance diodes, also known as varactors, are semiconductor devices whose capacitance varies with the applied voltage. They are used in frequency tuning applications, such as voltage-controlled oscillators (VCOs), frequency modulators, and RF filters. Varactors provide precise and adjustable capacitance, allowing for dynamic tuning and frequency control in electronic circuits. Their ability to provide reliable and stable performance makes them essential for applications requiring variable capacitance.
