Abstract

Systems and methods for automatically controlling one or more parameters of a digital phase-locked loop (DPLL) circuit are provided. A phase error signal generated by a phase detector of the DPLL circuit is received. A delayed version of the phase error signal is generated. A product of the phase error signal and the delayed version of the phase error signal is generated. The product is integrated, and a first output for controlling a gain of a proportional path of the DPLL circuit is generated based on the integrated product. The first output is down-sampled. A least-mean-square (LMS) filter is used to generate a second output that minimizes a value of the down-sampled output. A gain of an integral path of the DPLL is controlled based on the second output.
