1. An implantable stimulator device (ISD) configured to provide stimulation between at least a first electrode and a second electrode, comprising:

  • logic configured to define a group of a plurality of constant current pulses in a single timing channel, wherein the pulses are either only anodic or only cathodic, and wherein the pulses within the group have a second frequency greater than or equal to 2000 Hz; and

    source or sink circuitry configured to periodically apply the group of the pulses to the first electrode at a first frequency, wherein the second electrode comprises the other of an anode or cathode compared to the pulses in the group.
