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.

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 ...

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 ...

This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the ...

IC designer Don Sauer saw my blog about the difficulties of simulating PLLs and sent me a SPICE file (zip) of a basic PLL that you can play with. Don writes: I have a simple spice netlist for a PLL ...

[Kenneth Finnegan] put up a lengthy primer on PLLs (Phase-Locked Loops). We really enjoyed his presentation (even the part where he panders to Rigol for a free scope… sign us up for one of those too).

Some brief theory and typical measurements of phase noise. How to produce the lowest phase noise at a PLL output. A standard design procedure for a typical Type 2, second-order loop. As stated in ...

The MAP estimator form is used for the estimation of random parameters whereas the maximum-likelihood (ML) form is generally associated with the estimation of deterministic parameters. From Bayes Rule ...

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 – ...

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 ...
