Abstract: The tutorial overviews the basics of digital fractional-N phase-locked-loop architectures and their design principles from the signal-processing level down to circuit design. We will examine ...

Few topics in electrical engineering have demanded as much attention over the years as the phase-locked loop (PLL). The PLL is arguably one of the most important building blocks necessary for modern ...

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).

In this project, we designed an All-Digital Phase-Locked Loop (ADPLL) in Verilog and HSPICE. The ADPLL is composed of a Digital-Controlled Oscillator (DCO), a Phase-Frequency Detector (PFD), a ...
