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.

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.

Abstract: An implantable medical device (IMD) includes multiple stimulation engines (SEs) for independently stimulating respective electrode sets of a lead system. A voltage multiplier (VM) is configured to generate an adjustable target voltage at an output node. Each stimulation engine includes first switching circuitry to switchably connect an anodic node of the SE to the VM output node and second switching circuitry to switchably connect a cathodic node of the SE to a current sink circuit. Discharge switching circuitry may be disposed between the anodic and cathodic nodes of each SE. A selector and associated digital control logic block are operative to generate control signals for independently controlling respective SEs such that each SE may be activated to stimulate or discharge a corresponding select set of electrodes independently from or in concert with remaining SEs.
