Introduction of VCOs (Voltage Controlled Oscillators)

Voltage Controlled Oscillators (VCOs) are a class of oscillators used to generate and control a wide variety of waveforms. They are used in various applications, such as clocks and timers, frequency synthesizers, audio synthesizers, and other communication system applications. The most commonly used VCO is the phase-locked loop (PLL) VCO.

Working Principle of VCOs

VCOs are based on phase-shift oscillators, which use phase-shift networks that can be constructed from filter elements such as RC networks or active filter building blocks. The phase-shift networks increase or decrease the phase shift between the input signal and the output signal. This change in the phase shift causes the output signal of the VCO to switch polarity and may result in a frequency shift of the output signal.The frequency range of VCOs is usually determined by their active circuit element, such as the operational amplifiers used within the loop. The PLL VCO is typically rated up to a few hundred kHz, while the discrete VCOs can cover much higher frequency ranges.
