环形振荡器是计算机硬件组成电路的重要组成部分,承载着信号输出和信号放大的作用.文章探寻环形振荡器电路延迟效应的成因,同时分析缩短这类电路延迟时间、提高电路运行效率的方法.在环形振荡器电路中,逆变器的电容量和尺寸是影响电路参数的两个关键因素.为了准确分析出这两个因素对振荡器电路中延迟参数的影响,文章通过保持固定数量的逆变器,来观察电路逆变器尺寸对电路延迟参数的影响;另一方面,通过固定逆变器的尺寸,来分析电路中逆变器数量对电路延迟参数的影响.通过这两个方面的测试,可以得出环形振荡器对电路延迟效应的影响.%Ring oscillator is an important component of the circuit consisting computer hardware, which functions as signal output and amplification. The paper seeks out delay parameters of oscillator which have ef-fect on the delay of whole circuit when running the simulation by using ring oscillator circuit. The number of in-verters in the oscillator circuit and the size of the inverters are key points based on the structure of oscillator. By keeping the numbers of inverters fixed, one could observe the delay due to the change of size for each inverter. On the other hand, the effect on the delay for oscillator can be found to complete a whole logic process by vary-ing the numbers of the inverters while making the size remained. During this two comparison process, the cause of the delay time change in an oscillator can be obtained.
