摘要
介绍了一种由多级2/3分频单元级联的可编程分频器,可应用于扇出缓冲器的通道中。分频器采用0.18μm BiCMOS工艺实现。分频器的电源电压为3.3 V,分频比支持1、3、5以及4~4094的所有偶数分频,且所有分频输出信号的占空比为50%。
A programmable frequency divider based on multistage 2/3 cells was introduced in this paper,which could be applied in the channel of fan-out buffer.The frequency divider was realized by 0.18μm BiCMOS technology.The power supply voltage of the frequency divider is 3.3 V,the divi⁃sion ratios are including 1,3,5 and all even numbers from 4 to 4094,and the duty cycle of the output signal is 50%at all these division ratios.
