The 74HC/HCT4046A are phase-locked loop (PLL) with linear voltage-controlled oscillator (VCO) CMOS device having pins suited to 4046 in a 4000B series. These devices comply to JEDEC standard no. 7A.

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 phase-locked loop (PLL) is a feedback system that combines a voltage-controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or ...

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 ...

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 ...

…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).

[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).

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 ...

Austin, Nov. 06, 2025 (GLOBE NEWSWIRE) -- Phase-Locked Loops Market Size & Growth Insights: According to the SNS Insider,“The Phase-Locked Loops (PLL) Market Size was valued at USD 2.29 billion in ...

That big grandfather clock in the library might be an impressive piece of mechanical ingenuity, and an even better example of fine cabinetry, but we’d expect that the accuracy of a pendulum timepiece ...
