1. An implantable device for delivering a neural stimulus, the device comprising:
an array of electrodes; and
a processor configured to:
cause a first electrode of the array to deliver a first stimulus component of the neural stimulus and a third electrode of the array to deliver a third stimulus component of the neural stimulus simultaneously with the first stimulus component, the first stimulus component and the third stimulus component being of a first polarity, and
cause a second electrode of the array in between the first electrode and the third electrode to deliver a second stimulus component of the neural stimulus simultaneously with the first stimulus component and the third stimulus component, the second stimulus component being of a second polarity opposite the first polarity,
wherein the first, second, and third stimulus components are charge balanced, and
wherein the first stimulus component delivers a first charge which is unequal to a third charge delivered by the third stimulus component, the second stimulus component delivers a second charge, and the first charge and the third charge are selected so as to give rise to reduced artefact.
