These voltage controlled oscillators vcos are improved versions of the original vco family.
The figure below shows a simple voltage control oscillator using astable multivibrator.
For now you can imagine a voltage controlled oscillator vco to be a black box which takes in voltage of variable magnitude and produces.
The frequency of this waveform is varied by varying the magnitude of the input voltage.
This frequency is often used to keep track of time as in quartz wristwatches to provide a stable clock signal for digital integrated circuits and to stabilize frequencies for radio transmitters.
Voltage controlled oscillator info.
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.
The output frequency is determined by this master oscillator and an internal frequency divider n div pro.
Consequently a vco can be used for frequency modulation fm or phase modulation pm by applying a modulating signal to the control input.
A voltage controlled oscillator is an oscillator which produces oscillating signals waveforms with variable frequency.
Highly stable operation over specified temperature and or supply voltage ranges.
