锁相环是现代通信系统的基本构建模块,而电源噪声越来越影响锁相环性能。本文通过列举多种电源管理电路设计的新方法,解析不同的设计对锁相环性能产生的影响。
Phase-locked loop is the basic building blocks of modern communication systems, and power supply noise more and more affect the performance of the phase-locked loop. In this paper, by enumerating a variety of new methods of power management circuit design, the effects of different designs on the performance of a phase-locked loop are analyzed.
