A Background Jitter Calibration for ADCs Using TDC Phase Information From ADPLL

open access: yesIEEE Access
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

Evaluation of Adaptive Loop-Bandwidth Tracking Techniques in GNSS Receivers

open access: yesSensors, 2021
Global navigation satellite system (GNSS) receivers use tracking loops to lock onto GNSS signals. Fixed loop settings limit the tracking performance against noise, receiver dynamics, and the current scenario. Adaptive tracking loops adjust these settings
