DOI: 10.1109/tcsii.2021.3094932
Abstract: This work presents a low-noise millimeter-wave fractional-N digital frequency synthesizer architecture. It is formed by cascading an injection-locked frequency multiplier, an open-loop digital frequency synthesizer and an integer-N LC digital phase-locked loop. Though the individual… read more here.
