Time-mode techniques for fast-locking phase-locked loops

Abstract

A fast-locking phase-locked loop (PLL) with variable loop dynamics is proposed. The PLL employs a time amplifier (TA) with a variable gain to amplify the phase difference between the reference clock and the output of the voltage controlled oscillator (VCO). It operates by dynamically increasing the bandwidth of the PLL during locking state to speed up… (More)
