I have always had a soft spot for phase-locked loops – at least, I have since I first found out what they were. What I like about them is that they servo into the best answer for a given situation – ...

Scientists have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth ...

The clever part of a PLL can be found in how it looks at the phase of two signals. For signals to be totally in phase, they must be at the same frequency and also must ebb and peak at the same point.

The lock detector monitors the current status of PLL by comparing the phase difference of VCO divided signal and reference oscillator signal with required value.

Learn about the working principles of Phase-Locked Loops (PLL) and why they are widely used for applications where frequency tracking, resonance driving, and oscillator control are required.

A PLL is made up of three parts: a phase detector, a low pass filter, and a voltage controlled oscillator. It can do really neat things, like multiply clock speed (you see them in beefier chips ...

On the pll front, one of the things so admirable in the 4046 is phase comparator II – the one I was thinking of exploiting in the motor control. Unlike a multiplier or ex-or gate, phase comparator II ...
