Abstract
A charge balancing circuit is adapted to be connected to an electrode and to a stimulation source. The charge balancing circuit has an electrode terminal for receiving an electrode voltage, an amplifier coupled to the electrode terminal and adapted to amplify and invert the electrode voltage for generating an intermediate voltage and a compensation stage. The compensation stage is adapted to generate an output current if the electrode voltage lies outside a specified safety range and to generate the output current depending on the intermediate voltage. The compensation stage is further adapted to supply the output current to the electrode terminal for driving the electrode voltage towards and/or into the safety range.
