Abstract: A circuit may include a digitally-controlled oscillator including a coarse frequency-tuning array with a multiple selectable coarse frequency-tuning segments. Each of the coarse frequency-tuning segments may have a coarse segment frequency step size. The digitally-controlled oscillator may also include a fine frequency-tuning array with multiple selectable fine frequency-tuning segments. The fine frequency-tuning array may have a fine array frequency step size that is at least twice the coarse segment frequency step size. The digitally-controlled oscillator may be configured to generate an output signal with a frequency based on the coarse frequency-tuning array and the fine frequency-tuning array.
