Abstract
A phase-locked loop utilizes a pair of diodes in a loop filter design for providing fast acquisition of a reference signal during an acquisition mode, while maintaining a more narrow bandwidth in a locked mode of operation. During the acquisition mode, the diodes are conducting and the loop filter bandwidth is wide, which provides for a faster response time. As the reference signal is acquired, the diodes no longer conduct and the loop filter bandwidth becomes more narrow for tracking the reference signal.
