Abstract: An arrangement for electrical charge equalization after generation of stimulation current pulse(s), containing a bridge circuit, switching elements, a bridge branch between two legs of the bridge circuit, into which a load resistance is introducible, and a power source for generating a stimulation current pulse, connected to the legs of the bridge circuit that enables an electrical current via one leg through the bridge branch and through a leg connected to the other end of the bridge branch with corresponding switch position. A capacitive element is in the bridge branch for generating a current for electrical charge equalization for current introduced by stimulation current pulse(s) and is configured such that, between one or more stimulation current pulses and a discharge of the capacitive element via stimulation electrode(s), a delay time window is maintained, which is used for measuring electrical physiological signals induced as a reaction to the stimulation current pulse(s).

Abstract: An arrangement, configured for electrical charge equalization after the generation of one or more stimulation current pulses, containing a bridge circuit, switching elements, a bridge branch between two legs of the bridge circuit, into which a load resistance can be introduced, and at least one power source for generating at least one stimulation current pulse, which is connected to the legs of the bridge circuit in such a way that it enables an electrical current via one leg through the bridge branch and furthermore through a leg connected to the other end of the bridge branch with corresponding switch position.
