Abstract
Apparatuses and methods are disclosed, including an apparatus that includes a differential driver with charge injection pre-emphasis. One such apparatus includes a pre-emphasis circuit and an output stage circuit. The pre-emphasis circuit is configured to receive differential serial signals, and buffer the differential serial signals to provide buffered differential serial signals. The output stage circuit is configured to receive the buffered differential serial signals and drive the buffered differential serial signals onto differential communication paths. The pre-emphasis circuit is configured to selectively inject charge onto the differential communication paths to assist with a signal transition on at least one of the differential communication paths. Additional embodiments are disclosed.
