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 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 ...

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 ...

A general-purpose vector signal analyzer offers a low-cost, flexible option for measuring the frequency settling time of PLLs. By Douglas Olney, Keithley Instruments Inc. The frequency-settling time ...

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.

The phase locked loop, or PLL, is a real workhorse of circuit design. It is a classic feedback loop where the phase of an oscillator is locked to the phase of a ...

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 ...
