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 ...

LOS ALTOS, California, May 5, 2003 – True Circuits, Inc. (TCI), a leading provider of analog and mixed-signal intellectual property (IP) for the semiconductor and systems industries, today announced ...

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 ...

San Mateo, Calif. – Phase-locked and delay-locked loops are becoming increasingly important weapons in the system-on-chip design arsenal, but PLLs and DLLs are notorious for their difficulty. Now, ...

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 ...

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 ...

…which would take a pulse-width-modulated waveform at any frequency, and produce a signal with exactly the same mark/space ratio, but at a nominated frequency (see ‘Why might this be useful?’ below).
