Voltage Controlled Oscillator Circuit Diagram

The applied input voltage determines the instantaneous oscillation frequency.

Voltage controlled oscillator circuit diagram.

The ic has a very linear modulation characteristic and has excellent thermal stability. This waveform can either be of sine triangle or even a saw tooth type. Some of the most common oscillator circuits are lc circuit tank circuit etc. The circuit diagram of a voltage controlled oscillator using lm566 is shown in the figure below.

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. A voltage controlled oscillator is an oscillator which produces oscillating signals waveforms with variable frequency. A lm566 is a voltage controlled oscillator ic unit which is built with internal circuitry to generate both triangular and square wave signals whose frequency is set or adjusted by external capacitor and resistor followed with an application of dc voltage. The oscillation frequency varies from few hertz to hundreds of ghz.

A voltage controlled oscillator vco is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The lm566 ic can be operated from a single supply or dual supply. Voltage controlled oscillator using lm566. By varying the input dc.

The frequency of this waveform is varied by varying the magnitude of the. A vco is also an integral part of a phase locked. 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.
