摘要

延长电池使用时间和快速唤醒时间是移动消费电子设备的重要特征。当锁相环产生系统时钟时，采集时间可能会消耗睡眠周期的很大一部分，浪费了可以提供有用处理的能量。本文提出了一种锁相环结构，与现有锁相环相比，锁相环的锁相时间至少提高了一个数量级。

A fast-locking PLL architecture for efficient cycling of power-saving states in mobile electronic devices

Extended battery operation and quick wake-up time are important features in mobile consumer electronic devices. When a PLL generates the system clock, acquisition time can consume a significant portion of a sleep cycle, wasting energy that could provide useful processing. This paper presents a PLL architecture that improves lock time by at least an order of magnitude compared to an existing PLL.
