Abstract
An integrated semiconductor circuit has at least two supply networks that are supplied independently of one another. The two supply networks include a first, load supply network, which is associated with a load circuit, and a second, driver supply network, which is associated with a driver circuit. Each supply network has a ground path with ground lines and a supply path with supply potential lines which are separate from the ground path. A compensating circuit is provided which alternatively couples the ground paths and/or the supply paths of the at least two supply networks to one another.
