Voltage Controlled Oscillator Circuit Diagram

The frequency of this waveform is varied by varying the magnitude of the.

Voltage controlled oscillator circuit diagram.

This waveform can either be of sine triangle or even a saw tooth type. The applied input voltage determines the instantaneous oscillation frequency. The lm566 ic can be operated from a single supply or dual supply. By varying the input dc.

A voltage controlled oscillator vco is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The circuit diagram of a voltage controlled oscillator using lm566 is shown in the figure below. It is an oscillator whose output frequency is directly related to the voltage at its input. Some of the most common oscillator circuits are lc circuit tank circuit etc.

Voltage controlled oscillator using lm566. A voltage controlled oscillator is an oscillator which produces oscillating signals waveforms with variable frequency. A voltage controlled oscillator is an oscillator with an output signal whose output can be varied over a range which is controlled by the input dc voltage. Consequently a vco can be used for frequency modulation fm or phase modulation pm by applying a modulating signal to the control input.

While using a single supply the supply voltage range is from 10v to 24v. The oscillation frequency varies from few hertz to hundreds of ghz. Voltage controlled oscillator vco from the name itself it is clear that the output instantaneous frequency of the oscillator is controlled by the input voltage it is a kind of oscillator which can produce output signal frequency over a large range few hertz hundreds of giga hertz depending on the input dc voltage given to it.
