Pv. Brennan, PERFORMANCE OF PHASE-LOCKED LOOP FREQUENCY-SYNTHESIZER USING ACCUMULATIVE PHASE-DETECTOR, IEE proceedings. Circuits, devices and systems, 143(5), 1996, pp. 249-254
The performance of phase-locked loop circuits is critically dependent
on the phase detector design. The author considers the use of an unusu
al phase detector that is capable of linear operation over an arbitrar
ily wide operating range. This provides the benefits of analytically p
redictable transient behaviour, without cycle slipping, under all like
ly conditions of operation and with the prospect of improved acquisiti
on speed. The behaviour of phase-locked loops incorporating such a des
ign is demonstrated analytically and subsequently confirmed by experim
ental results.
