Abstract

A distribution current is split into a first control current, a second control current, and a third control current, in an apportionment according to a distribution command. A first control voltage is generated in response to the third control current. A second control voltage is generated as indication of the first control current, and a third control voltage is generated as indication of the second control current. Optionally, de-emphasis contribution of a first driver, a second driver and a third driver to an output is controlled based, at least in part, on the first control voltage, the second control voltage and the third control voltage, respectively.
