We present a design for an adaptive gain phase-locked loop (PLL) that features fast acquisition, low jitter, and wide tuning range.

提出了一种快捕获，低抖动，宽调节范围的增益自适应锁相环的设计。

Because of the merit of integrated easily, low power, low jitter, small phase difference error and big capture scale, the CPPLL (Charge-pump PLL) has become one of the major digital PLL product.

电荷泵锁相环具有易于集成、低功耗、低抖动、频率牵引范围大和静态相位误差小等优点，成为了当前数字锁相环产品的主流。
