Few topics in electrical engineering have demanded as much attention over the years as the phase-locked loop (PLL). The PLL is arguably one of the most important building blocks necessary for modern ...

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.

I ran across a really good article about simulating phase-locked loops in Wireless Design and Development magazine. Andy Howard wrote it over at Agilent. Phase lock loops or PLLs are a very difficult ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

Some brief theory and typical measurements of phase noise. Standard analysis of PLL phase noise used by most CAD applications. How to produce the lowest phase noise at a PLL output. A standard design ...

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 – ...
