摘要
本文设计了一种稳定电压源、补偿温度和工艺变化的压控环振荡器稳频电路。在振荡器中引入了带隙基准电压的线性电压源和用于调节控制电压的温度和过程补偿电路。仿真结果表明，当所提出的振荡器设置为620 MHz时，当温度为27℃，典型的过程角时，电压源在3.0 V ~ 3.6 V范围内的输出频率变化为0.13%;电压源为3.3 V，典型工艺角时，在0℃~ 120℃温度范围内，输出频率变化为0.8%;在温度为27℃时，对所有工艺角加入补偿电路后，输出频率变化由34.3%增加到19.1%。
A Frequency Stabilization Circuit for The Voltage Controlled Ring Oscillator
A design of a frequency stabilization circuit for the voltage controlled ring oscillator that can stabilize the voltage source and compensate the temperature and process variation is presented here. A linear voltage source using bandgap voltage reference and a temperature and process compensated circuit used for adjusting the control voltage are introduced into the oscillator. The simulation results show that when the proposed oscillator is set at 620 MHz, the output frequency has a variation of 0.13% for the voltage source in the range 3.0 V to 3.6 V when the temperature is 27degC and the process corner is typical; the output frequency has a variation of 0.8% for the temperature range of 0degC to 120degC when the voltage source is 3.3 V and the process corner is typical; the output frequency variation changes from 34.3% to 19.1% after the compensation circuit is added for all the process corners when the temperature is 27degC.
