All-Digital Phase Locked Loop (ADPLL) as an Intellectual Property (IP) Core for an Application-specified Integrated Circuit (ASIC) Product: A Survey

Abstract

An all-digital phase locked loop (ADPLL) plays a great role in decreasing the developmenttime of an application-specified integrated circuit (ASIC) products and helps to meet the timetomarket requirement of product, because an ADPLL can be used as an IP core, so it is easilyreusable in any design. Now a days ADPLL is being widely used in various fields such ascontrol systems and digital communication systems. This survey paper presents the basicdetails of ADPLL and its recent developments in ADPLL. Implementation and function ofeach component of ADPLL has been described separately.
