Continuous comparator with improved calibration

摘要

An auto-calibrated current sensing comparator (100,200) is provided. A secondary dynamic comparator (110) shares the same inputs and acts to adjust a calibration control of the current sensing comparator (100,200). The calibration control may be in the form of adjusting the offset (102) of the current sensing comparator or adjusting a propagation delay (204) that is added to its output.
