Linearized discrete-time model of higher order charge-pump PLLs

Bi, Chuang ; Curran, Paul F. ; Feely, Orla (IEEE, 2011-08-29)

In this paper, we derive linearized discrete-time models of higher order Charge-Pump Phase-Locked Loops (CPPLLs). The behaviour of CP-PLLs in the steady state is analysed and an important feature is developed. The nonlinear ...
Nonlinear dynamics of alias-locked loop

Bi, Chuang ; Feely, Orla (IEEE, 2009-08-23)

This paper examines the nonlinear dynamics of an alias-locked loop (ALL) which uses an aliasing divider instead of a traditional frequency divider in the feedback loop of a phaselocked loop. A nonlinear model of the ALL ...
