Abstract
Receiver circuitries having multiple branches, such as unrolled feedback equalizers and fractional-rate receivers, may present differences between filtering elements of different branches with common filter inputs. Embodiments include devices capable of calibration that compensates such differences. The devices may be capable of introducing front-end offsets to emphasize the mismatches, and sweep filter input values to calculate the mismatches, and introducing offsets in the branches to compensate for the mismatches. Methods for use of the calibration devices are also described.
