Abstract

An example output driver includes a plurality of output circuits coupled in parallel between a first voltage supply node and a second voltage supply node. Each of the plurality of output circuits includes a differential input that is coupled to receive a logic signal of a plurality of logic signals and a differential output that is coupled to a common output node. The output driver further includes voltage regulator(s), coupled to the voltage supply node(s), and a current compensation circuit. The current compensation circuit includes a switch coupled in series with a current source, where the switch and the current source are coupled between the first voltage supply node and the second voltage supply node. An event detector is coupled to the switch to supply an enable signal and to control state of the enable signal based on presence of a pattern in the plurality of logic signals.
