Abstract
An output buffer for providing a buffered current to a circuit load includes a plurality of operative stages, each one for generating a component of the buffered current and an enabling circuit for selectively enabling each operative stage. The output buffer further comprises at least one auxiliary stage and control means for measuring a control current that can be delivered by the at least one auxiliary stage and for activating the enabling means according to the measured control current.
