Abstract
An apparatus for processing data includes a decision feedback equalizer configured to sample an analog signal to yield digital data and a DC offset adaptation circuit. The decision feedback equalizer is configured to sample the equalized signal using at least one data latch at a first data latch threshold value and at a second data latch threshold value. The DC off set adaptation circuit is configured to calculate a DC off set in the analog signal based on the first data latch threshold value and on the second data latch threshold value.
