Phase-locked loop design for on-chip tuning applications

A novel phase-locked loop scheme is proposed, the main application of which is in on-chip tuning circuits. It involves the use of a variable gain amplifier and also a frequency tunable loop filter, providing infinite hold-in range, a fractionally constant pull-out range and also a fractionally const...

Zusammenfassung:A novel phase-locked loop scheme is proposed, the main application of which is in on-chip tuning circuits. It involves the use of a variable gain amplifier and also a frequency tunable loop filter, providing infinite hold-in range, a fractionally constant pull-out range and also a fractionally constant ripple.
