Synchronized state in networks of digital phase-locked loops
Clock distribution networks of synchronized oscillators are an alternative approach to classical tree-like clock distribution methods. Each node of the network may consist of a phase-locked loop (PLL) trying to match the phase of its neighbors. Then a network of independent oscillators takes the place of the centralized clock source, providing separate

A Background Jitter Calibration for ADCs Using TDC Phase Information From ADPLL
The phase noise, commonly known as jitter, in Phase-Locked Loops (PLLs) is conventionally perceived as a stochastic process, necessitating a degree of tolerance in downstream circuits such as Analog-to-Digital Converters (ADCs). This paper addresses this

FPGA implementation of impedance-compensated phase-locked loop for HVDC converters
The phase-locked loop (PLL) plays a key role in HVDC systems. Recently, a new type of PLL called the impedance-compensated phase-locked loop (IC-PLL) was introduced to compensate for the voltage drop across the AC network's Thevenin impedance, making the

Millimeter-Wave All-Digital Phase-Locked Loop Using Reference Waveform Oversampling Techniques
This article proposes an mm-wave fractional-N all-digital phase-locked loop (ADPLL) employing a reference-waveform oversampling (ROS) phase detector (PD) that increases its effective rate four times, consequently improving jitter at lower power ...
