Abstract

A digital phase-locked loop (DPLL) may include a dithering source to provide a dithering signal that is on an order of up to one integer bit on a set of fractional bits of a modulation signal. The DPLL may include a digitally controlled oscillator (DCO) to generate a DPLL output signal. The DPLL may include a primary delta-sigma modulator (DSM) to drive a primary capacitor bank of the DCO based on the dithering signal and the modulation signal, a first auxiliary DSM to drive a first auxiliary capacitor bank of the DCO based on the dithering signal in association with cancelling an effect of the dithering signal on the DPLL output signal, and a second auxiliary DSM to drive a second auxiliary capacitor bank of the DCO based on the modulation signal and the dithering signal in association with cancelling an effect of a quantization error of the primary DSM.
