This application note discusses phase frequency detector characteristics that affect phase-locked loop (PLL) dead band and jitter performance. In PLLs that employ charge pump loop filter designs the ...
Phase-locked-loop (PLL) frequency synthesizers are signal sources often employed in many types of electronic equipment. They show up as clock sources in high-frequency instruments and as local ...
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 ...
Combating fractional spurs in phase locked loops to improve wireless system performance in Beyond 5G
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 ...
The phase-locked loop (PLL) has become one of the most versatile tools in the communication sector. PLLs are at the heart of circuits and devices ranging from clock recovery blocks in data ...
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 ...
