새로운 듀얼 슬로프 위상 주파수 검출기를 이용한 위상고정 시간이 빠른 위상고정 루프

Abstract

This paper presents a new fast locking phase-locked loop. Although the conventional fast phase-locked loop has two tuning loops, a proposed phase-locked loop was realized using just one tuning loop. The proposed circuit was simulated by HSPICE with a standard CMOS 0.25㎛ process parameter.
