ABSTRACT:
A phase-lock loop includes a scaling element whose scale factor is adaptively adjusted as a function of the value of a state variable in the loop--illustratively, the magnitude thereof. That function is such that, after the adjustment has been made, the value taken on by the state variable is within a predetermined range. In particular embodiments, the scale factor and the state variable are simultaneously adjusted reciprocally, rather than simply adjusting only the scale factor and waiting for the normal operation of the loop to change the state variable, advantageously minimizing any transient degradation in loop performance that may occur as a result of the adjustment.
