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 ...

[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).

As clock speeds and communication channels run at ever higher frequencies, engineers who have previously had little need to consider clock jitter and phase noise are finding that they need to increase ...

Two innovative design techniques lead to substantial improvements in performance in fractional-N phase locked loops (PLLs), report scientists from Tokyo Tech. The proposed methods are aimed to ...

If you want a stable oscillator, you usually think of using a crystal. The piezoelectric qualities of quartz means that it can be cut in a particular way that it will oscillate at a very precise ...

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 ...

Related to my search for reduced motor noise (and thanks to all who have made suggestions – ‘scope avaunt this weekend), is a search for speed stability in that motor*. And to someone who is in love ...

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 ...
