In this post I have explained how to build 6 useful voltage controlled oscillator circuits, using various op amps and integrated circuits. As the name suggests, a voltage controlled oscillator or a VCO circuit is an oscillator circuit whose output frequency can be controlled or varied through an adjustable control voltage input. This means, if […]
