Abstract: A serial data receiver is disclosed. In one embodiment, a receiver includes an amplifier circuit configured to receive one or more signals that encode a serial data stream that includes a plurality of data symbols and to perform a comparison of the one or more signals to a threshold value to generate a recovered data symbol. The receiver circuit further includes a threshold circuit configured to generate a delayed version of the one or more signals. The threshold circuit is further configured to generate a delayed data symbol using the delayed version of the one or more signals and adjust the threshold value using the delayed data symbol.
