context_page_description: A voltage-controlled oscillator is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The applied input voltage determines the instantaneous oscillation frequency. Consequently, a VCO can be used for frequency modulation or phase modulation by applying a modulating signal to the control input. A VCO is also an integral part of a phase-locked loop.
  A voltage-to-frequency converter is a special type of VCO designed to be very linear in frequency control over a wide range of input control voltages.

The applied input voltage determines the instantaneous oscillation frequency.  Consequently, a VCO can be used for frequency modulation (FM) or phase modulation (PM) by applying a modulating signal to the control input.  A VCO is also an integral part of a phase-locked loop.
  A voltage-to-frequency converter (VFC) is a special type of VCO designed to be very linear in frequency control over a wide range of input control voltages.
