A voltage-controlled oscillator (VCO) is an electronic oscillator whose oscillation frequency is controlled by a voltage input. 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

2021年10月26日 · In this post I have explained how to build 6 useful voltage controlled oscillator circuits, using various op amps and integrated circuits. As the name suggests, a voltage controlled oscillator or a VCO circuit is an oscillator circuit whose output frequency can be controlled or varied through an adjustable control voltage input.

2012年2月24日 · 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. Many forms of …

2020年3月17日 · 压控振荡器（Voltage Controlled Oscillator，VCO）是锁相环（PLL）的主要组成部分之一。它能在有限的频率范围内产生频率，通常高于参考振荡器的频率。VCO的频率是可调的，通过改变输入调谐电压来控制。这个频率会随着温度、电源电压或半导体工艺的变化而发生 ...

2021年1月26日 · 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.

Definition: VCO is an acronym for Voltage Controlled Oscillator. It is a device that produces such an oscillating output signal whose frequency can be regulated or altered by the input dc voltage. In other words, we can say, VCO generates an output signal having an adjustable frequency range that is controlled by the dc input voltage.
