摘要

本文提出了一种采用注入锁紧技术的压控振荡器(VCO)的设计方法。采用SCL 180nm CMOS工艺，利用Cadence Virtuoso模拟设计环境对电路进行仿真。仿真结果表明，该VCO在508 MHz ~ 3.56 GHz范围内实现了150%的调谐范围，在1 MHz偏移频率下相位噪声为- 126 dBc/Hz。电源电压为1.8时，电路功耗为110.4 μW。

A wide tuning range voltage controlled ring oscillator using injection locking

In this paper design of Voltage Controlled Oscillator (VCO) using injection locking technique is proposed. The circuit simulation is done by Cadence Virtuoso Analog Design Environment using SCL 180nm CMOS process. Simulation results shows that the VCO achieves tuning range of 150% over the range of 508 MHz to 3.56 GHz with the phase noise of −126 dBc/Hz at 1 MHz offset frequency. The power dissipation of the circuit is 110.4 μW from 1.8 supply voltage.
