Voltage-Controlled Oscillator

A voltage-controlled oscillator changes the resonant circuit parameters via voltage to control the output frequency variation. It is used for frequency modulation in communication systems, synchronization in phase-locked loops, and frequency modulation in signal generators. It enables linear conversion from voltage to frequency in radio equipment and testing instruments.
Selection
When selecting a voltage-controlled oscillator, it is essential to consider that the frequency range covers the operational requirements, the tuning voltage and linearity match the control circuit, the phase noise meets the system's signal-to-noise ratio requirements, the power supply voltage and power consumption are compatible with the device's power supply conditions, and the package size fits the circuit board space.
