What is VCOs?

A Voltage-Controlled Oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The frequency of oscillation varies in proportion to the applied voltage. VCOs are used in many applications, including function generators, phase-locked loops (PLLs) used in radio receivers, and frequency synthesizers.
