1. A neurostimulation system, comprising:

  • a grounding electrode configured for being placed in contact with neural tissue;

    a plurality of electrical terminals configured for being respectively coupled to an array of electrodes;

    a first regulator configured for being electrically coupled between an anode of the electrodes and the grounding electrode;

    a second regulator configured for being electrically coupled between a cathode of the electrodes and the grounding electrode; and

    control circuitry configured for controlling the first and second regulators to convey electrical stimulation energy between the anode and the cathode, such that an average shift in voltage on the anode and cathode relative to the grounding electrode is equal to or less than one half a differential voltage between the anode and cathode.
