Abstract: A fast locking all-digital phase-locked loop (ADPLL) via feed-forward compensation technique is proposed in this paper. The implemented ADPLL has two operation modes which are frequency ...

This Frontiers Research Topic will spotlight advances in the newly emerging field of Closed-Loop Neurophysiology. The basic paradigm involves recording neural activity or behavior and delivering ...

Abstract: This article presents a quadrature phase-locked-loop (QPLL)-based digital system for closed-loop control of micro-electromechanical system (MEMS) resonant sensors. The system estimates the ...
