Abstract
A receiver circuit includes a first slicer coupled to receive data signals from a signal path and a reference voltage from a reference voltage path that is separate from the signal path. The first slicer is configured output a logic value based on a comparison between a voltage of the data signal and the reference voltage. The receiver circuit further includes a reference voltage generator configured to generate the reference voltage. The reference voltage generator is configured to dynamically generate the reference voltage based on logic values of previously received signals during operation in a first mode. During operation in a second mode, the reference voltage generator is configured to generate and provide the reference voltage as a static voltage.
