Abstract
A system and method are provided that include a power supply having positive and negative terminals. The negative terminal defines a reference ground. First and second electrodes are positioned within a patient and configured to be located proximate to tissue of interest that is associated with a target region. A control circuit is configured to control delivery of current for a 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 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.
