The circuit shown is a RC oscillator. Find the frequency of oscillation in Hertz and the voltage gain, K, of the voltage amplifiers necessary for oscillation. The voltage amplifiers have infinite input resistance and zero output resistance. Solution The loop gain can be found from the schematic shown: T(s) = Vr Vx = K2 1 sRC+1

The circuit as shown in Figure below presents a 555 as an extremely simple, voltage-controlled oscillator (VCO). The VCO’s output frequency (U1) differs contrariwise with the input voltage. Using a 1 V input, the oscillator’s output frequency is around 1500 Hz. If you supply a 5-V input, the oscillator’s output frequency dips to about 300 Hz.

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 the input control voltage is increased, the output frequency will increase proportionately, and vice versa.
