Voltage Controlled Oscillator Circuit Diagram
The frequency of this waveform is varied by varying the magnitude of the.
Voltage controlled oscillator circuit diagram. The lm566 ic can be operated from a single supply or dual supply. This waveform can either be of sine triangle or even a saw tooth type. The ic has a very linear modulation characteristic and has excellent thermal stability. A vco is also an integral part of a phase locked.
A voltage controlled oscillator vco is an electronic oscillator whose oscillation frequency is controlled by a voltage input. The oscillation frequency varies from few hertz to hundreds of ghz. 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 applied input voltage determines the instantaneous oscillation frequency.
Consequently a vco can be used for frequency modulation fm or phase modulation pm by applying a modulating signal to the control input. The circuit diagram of a voltage controlled oscillator using lm566 is shown in the figure below. A voltage controlled oscillator is an oscillator which produces oscillating signals waveforms with variable frequency. Some of the most common oscillator circuits are lc circuit tank circuit etc.
Voltage controlled oscillator using lm566. By varying the input dc. It is an oscillator whose output frequency is directly related to the voltage at its input.
