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 ...

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 ...

You can see the videos below. 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 ...

One of the most challenging tasks in analog circuit design is to adapt a functional block to ever new CMOS process technology. For digital circuits the number of gates per square mm approx. doubles ...

The NB4N507A is a fully integrated phase lock loop (PLL) designed to replace expensive crystal oscillators for clock generation in a variety of consumer and networking applications. The IC generates a ...

The HEF4046B is a phase-locked loop circuit that contains a linear voltage-controlled oscillator (VCO) and two discrete phase comparators that has a common signal input amplifier and a common ...

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes 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 – ...
