Jan 26, 2021 · VCOs are specifically designed to produce an output signal whose frequency varies according to the amplitude of an input signal over a reasonable range of frequencies. VCOs come in discrete, modular, and monolithic forms, but a discussion of discrete VCOs will provide a basic understanding of how they operate and why certain specifications matter.
Voltage Controlled Oscillator | VCO - Electrical4U
Feb 24, 2012 · A voltage controlled oscillator (VCO) is defined as an oscillator whose output frequency is controlled by an input voltage. It can produce a wide range of frequencies, from a few Hertz to hundreds of Giga Hertz, based on the input DC voltage.
VOLTAGE CONTROLLED OSCILLATORS - electronics tutorials
A voltage controlled oscillator or as more commonly known, a vco, is an oscillator where the principal variable or tuning element is a varactor diode. The voltage controlled oscillator is tuned across its band by a "clean" dc voltage applied to the varactor diode to vary the net capacitance applied to the tuned circuit.
