摘要
本论文提出了一种占空比为 5 0 %奇数分频器的实现方法 ,基于 0 2 5 μmCMOS工艺参数 ,使用CadenceSpectre对分频器进行了仿真 .当分频比为 5 ,电源电压为 2 5V ,工作温度为 2 7℃ ,分频器的输入频率为 6 5 0MHz时 ,输出信号的占空比可达 4 9 94 % .
A high frequency odd divider with nearly 50% duty is realized in this paper.Based on 0.25μm CMOS process model,the divider is simulated using Cadence Spectre.The simulation results show that the duty of the divider is 49.94% when the division ratio is 5,the power supply is 2.5V,the working temperature is 27℃ and the input frequency is 650MHz.
