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 ...

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 – ...

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 ...

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.

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 ...

The Intuitive Internet of Things, or I2oT, is a concept imec has been working to bring to fruition. Speaking at the imec Technical forum held in conjunction with SEMICON West 2015, Luc Van den hove, ...

…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).

Digital electronic devices form the backbone of modern technology, enabling the processing, storage, and transmission of information using binary signals. These systems, based on semiconductor ...
