Abstract: An apparatus and method for providing split stimulation currents in a pulse generator. In one embodiment, a current regulator of the pulse generator includes a digitally-programmable analog voltage generator coupled to a first input of an error amplifier that receives a second input controlled by a programmable resistor network configured to control a programmable total stimulation current output. A plurality of current splitting switches are operative to split the programmable total stimulation current output into a corresponding plurality of split current segments, which may be individually mapped to a selected set of lead electrodes across one or more implantable leads associated with the pulse generator.

Abstract: A neurostimulation (NS) system and method are provided. The system includes a power supply having positive and negative terminals. The negative terminal defines a reference ground. An array of electrodes are positioned within a patient. The array of electrodes includes first and second active electrodes for delivering stimulation therapy configured to be located proximate to neural tissue of interest that is associated with a target region. A control circuit is configured to control delivery of stimulation current for a NS therapy between the first and second electrodes. A current regulator (CR) circuit is connected to, and configured to control current flow through, at least the first electrode during delivery of the stimulation therapy under direction of the control circuit. A floating power supply is connected across power supply terminals of the CR circuit. The CR circuit and floating power supply are coupled to a floating ground node that is electrically separate from the reference ground.

Abstract: An implantable medical device (IMD) includes an adjustable capacitive voltage multiplier (CVM) that is responsive to diagnostic circuitry configured to provide control signals within a single stimulation current pulse for adjusting the voltage output applied to an electrode of the IMD's lead system. A control counter is coupled to the diagnostic circuitry for incrementing or decrementing an N-bit counter output signal operative to reconfigure a charge pump arrangement of the CVM so as to facilitate an adjusted voltage output.
