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 ...

But taking a voltage-controlled oscillator at 100 MHz (nominal) and dividing its output by 100 will give you a signal you can lock to a 1 MHz crystal oscillator which is, of course, trivial to build.

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. 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 ...

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 ...

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 – ...

Radiation-hardened phase-locked loop (PLL) circuits represent a critical advancement in safeguarding electronic systems against the deleterious effects of ionising radiation. These circuits are ...

Two innovative design techniques lead to substantial improvements in performance in fractional-N phase locked loops (PLLs), report scientists from Tokyo Tech. The proposed methods are aimed to ...

Related to my search for reduced motor noise (and thanks to all who have made suggestions – ‘scope avaunt this weekend), is a search for speed stability in that motor*. And to someone who is in love ...
