Abstract:
An example time-skew calibration circuit includes a plurality of first circuits, each including a first accumulator and a second accumulator. The time-skew calibration circuit further includes a plurality of second circuits, each including a first adder coupled to outputs of the first accumulator and the second accumulator, and a first subtractor coupled to the outputs of the first accumulator and the second accumulator. The time-skew calibration circuit further includes a decision circuit configured to combine an output of the first adder and an output of the first subtractor.
