Abstract

An inventive driver stage for driving an output on one of n-levels, which are each spaced from each other by a voltage difference of ΔV, includes a plurality of field effect transistors for driving the output by supplying or removing a current to or from the output, with the relationship of the channel widths of at least two field effect transistors, which both function either to lead a current to or away, being set in dependence on the value of the voltage difference.
