摘要
本文提出了一种快速响应锁相环的设计,采用电压/周期转换器作为控制部件,可以在参考脉冲的两个周期内使环路达到锁定,并解决了PLL低频稳定问题.实验验证了方案的正确性.
A fast-response phase-locked loop is presented by using a voltage-to-period converter as the controlled component. It can be settled in 2 cycles of the input signal for step response, and the unstable problem in the low-frequency range is solved. The experimental result shows that the design is correct.
