COMPLIANCE VOLTAGE MONITORING AND ADJUSTMENT IN AN IMPLANTABLE MEDICAL DEVICE USING LOW SIDE SENSING

An architecture is disclosed for an Implantable Pulse Generator having improved compliance voltage monitoring and adjustment software and hardware. Software specifies which stimulation pulses are to be measured as relevant to monitoring and adjusting the compliance voltage. During compliance voltage monitoring, "high-side" anode electrode node voltages referenced to the compliance voltage are considered as are "low-side" cathode electrode node voltages referenced to ground. Translation stages are used to convert only the anode electrode node voltages to ground as low-side signals. This allows compliance voltage monitoring and adjustment to occur using only low-side signals, which eases sensing and reduces design complexity.
