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 ...

The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

Editor's Note: Although the primary target market for the 86100CU-400 application presented below is for ASIC/SoC designs, I'm assured by the folks at Agilent that this application is also applicable ...

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 ...

For an IC building block that came into being at about the same time as the microprocessor in the late 1960s and early 1970s, the “lowly” phase-locked loop has not done too badly. The hidden beauty of ...

San Francisco, CA. At the 2017 International Solid-State Circuits Conference in San Francisco, imec, Holst Centre, and ROHM presented an all-digital phase-locked loop (ADPLL) for Internet-of-Things ...

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 ...

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 ...

Scientists have developed an advanced phase-locked loop (PLL) frequency synthesizer that can drastically cut power consumption. This digital PLL could be an attractive building block for Bluetooth Low ...

When Hackaday runs a contest, we see all manner of clever projects. But inevitably there are some we don’t see, because their builders didn’t manage to get them finished in time. [Park Frazer]’s phase ...

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 – ...
