At the heart of a clocking device is the phased-locked loop (PLL). A key part of the PLL is the loop filter, which converts correction currents from the PLL charge pump into a control voltage for the ...

In designing a simple spectroscopy setup, we needed to synchronize the speed of a small, inexpensive dc motor precisely to 6000 rpm (100 Hz). Our first idea was to take a phase-frequency detector type ...

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 ...

This is Part 2 of a three-part series. As discussed in Part 1 and recapped here, modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher ...
