1. An implantable stimulator device, comprising:

  • a plurality of electrode nodes implantable adjacent to tissue to be stimulated;

    programmable current source circuitry configured for sourcing a first one or more output currents respectively to a first one or more of the plurality of electrode nodes;

    programmable current sink circuitry configured for sinking a second one or more output currents respectively from a second one or more of the plurality of electrode nodes;

    control circuitry configured for programming the current source circuitry and the current sink circuitry, such that the a total sum of the first one or more output currents equals a total sum of the second one or more output currents in each of one or more channels.
