A 10.8–14.5-GHz Eight-Phase 12.5%-Duty-Cycle Nonoverlapping LO Generator With Automatic Phase-and-Duty-Cycle Calibration

Abstract: A 10.8–14.5-GHz eight-phase 12.5%-duty-cycle nonoverlapping LO generator is proposed for 60-GHz eight-path-filtering subsampling receivers. A four-stage ring oscillator (RO) is followed by ...
