VCO stands for Voltage Controlled Oscillator. VCO is an Oscillator of which frequency can be Controlled by external Voltage stimulus. One of major applications for VCO is a frequency synthesizer. Frequency synthesizer provides sinusoidal/pulse signals at predetermined frequencies that is precisely controllable by digital words.

This note will review the process by which VCO (Voltage Controlled Oscillator) designers choose their oscillator’s topology and devices based on performance requirements, components types and DC power requirements. Basic oscillator design specifications often require a given output power into a specified load at the design frequency.

The central reflection-based VCO design concept is the development of an active network presenting a near-voltage-independent susceptance (i.e., ∂Bd / ∂V | V = Vo ≈ 0) and a frequency-independent negative conductance (∂Gd / ∂ω | ω = ω0 ≈ 0).

1、电感选择smic13mmrf库中的 diff_ind_3t_rf_pgs，该电感含有3个端口，第三个端口可以接直流偏置，且品质因数比diff_ind_3t_rf更高，VCO需要的是高Q值的电感，因此选择diff_ind_3t_rf_pgs，参数设置如下

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.

VCO Type I To maximize tuning range, we wish to minimize C1. But C1 is given by: Caps of M1 and M2 (including 4Cgd) Cap of L1 Input cap of next stage

This repository contains the design and simulation results of a Voltage-Controlled Oscillator (VCO) based on a 5-stage ring oscillator in both 45nm and 180nm technologies. The purpose of this project is to compare the performance of the VCO …

Millimeter-wave transceivers have found their place in 5G radios operating around 30 GHz. In this article, we design a voltage-controlled oscillator (VCO) in 28-nm CMOS technology for such an environment.

为什么选vco? 主要还是简单， 不是说设计简单，是功能简单，输入简单，输出简单容易被非模拟背景的人理解。 另外vco似乎很多是 veriloga 实现的，网上依照一大堆， 可以先忽略设计细节，转而追求流程走一遍有上手经验。 也算是利用AI授己以渔
