We describe an architecture that adds a linear predictor and adaptive control to a comparator to greatly reduce its delay. The linear predictor feeds an estimated future signal to the comparator to compensate for the comparator’s inherent delay. On a cycle-by-cycle basis, an adaptive controller adjusts the comparator’s bias current to null residual errors… CONTINUE READING
