Abstract

A charge balancing circuit (CBC) adapted to be connected to an electrode (E) and to a stimulation source (CS) is provided. The charge balancing circuit (CBC) comprises an electrode terminal (ET) for receiving an electrode voltage (V E ), an amplifier (A) coupled to the electrode terminal (ET) and adapted to amplify and invert the electrode voltage (V E ) for generating an intermediate voltage (V in ) and a compensation stage (CP). The compensation stage (CP) is adapted to generate an output current (I out ) if the electrode voltage (V E ) lies outside a specified safety range and to generate the output current (I out ) depending on the intermediate voltage (V in ). The compensation stage (CP) is further adapted to supply the output current (I out ) to the electrode terminal (ET) for driving the electrode voltage (V E ) towards and/or into the safety range.
