Performance of phase-locked loop frequency synthesiser usingaccumulative phase detector

摘要

The performance of phase-locked loop circuits is criticallyndependent on the phase detector design. The author considers the use ofnan unusual phase detector that is capable of linear operation over annarbitrarily wide operating range. This provides the benefits ofnanalytically predictable transient behaviour, without cycle slipping,nunder all likely conditions of operation and with the prospect ofnimproved acquisition speed. The behaviour of phase-locked loopsnincorporating such a design is demonstrated analytically andnsubsequently confirmed by experimental results
