摘要

VCO在各种各样的应用中发挥着作用。压控振荡器产生的信号的频率取决于它的输入信号。为了使芯片面积最小，一般采用反相位耦合的方法。但在这种设计中，直流耦合和相位噪声较高。本文采用180nm技术，利用正交相位耦合和变压器来降低压控振荡器的相位噪声。给出了压控振荡器的直流和交流分析。在压控振荡器电路中引入注入锁的概念，减小了正交误差。

Transformer Coupled Voltage Controlled Oscillator Using 180nm Technology in Cadence Tool

VCO finds role in a wide variety of applications. The frequency of the signal generated by VCO depends on its input signal. Anti phase coupling is generally followed in VCOto obtain minimum chip area. But in such designs the dc coupling and phase noise is higher. In this work, quadrature phase coupling is used with the help of transformer to decrease phase noise in VCO and it is designed in cadence 180nm technology. The DC and AC analysis of VCO are shown. By the concept of injection locking in VCO circuit, the quadrature error is also reduced.
