1. An implantable medical device for delivering neurostimulation, comprising:
a pulse generator including an application specific integrated circuit (ASIC);
a number N of electrodes, wherein N is equal to or larger than 3; and
said ASIC configured to deliver, via each electrode of the N electrodes of the implantable medical device, a set of pulses including a therapeutic electric pulse and a number of N−1 charge balancing electric pulses, wherein the charge balancing electric pulses of the electrode each have a polarity being opposite to a polarity of the therapeutic electric pulse of the electrode, wherein a current of the therapeutic electric pulse is equal to a sum of currents of the charge balancing electric pulses.
