Abstract

A method and an apparatus for switching on a voltage supply of a voltage domain of a semiconductor circuit is disclosed. A voltage supply is connected to a supply voltage of the semiconductor circuit by means of a switchable element. The switchable element is activated in such a way that, for switching on the voltage supply of the voltage domain, a current through the switchable element rises progressively with at least one intermediate value, in particular stepwise manner.
