摘要

本文提出了一种新的相位频率检测器，通过避免在输入相位误差超出[-π， π]范围时产生复位信号，彻底消除了“盲区”。所提出的相频检测器具有良好的非线性传递特性，可以有效地加快锁相环的锁取速度。

A nonlinear phase frequency detector with zero blind zone for fast-locking phase-locked loops

This work proposes a new phase frequency detector, which completely eliminates the “blind zone” by avoiding generating the reset signal when the input phase error is out of the range of [-π, π]. The proposed phase frequency detector possesses a beneficial nonlinear transfer characteristic and can speed up the lock acquisition of a phase-locked loop effectively.
