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 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.
