ALGORITHM FOR ADJUSTING A COMPLIANCE VOLTAGE IN A STIMULATOR DEVICE HAVING NEURAL SENSING CAPABILITY

An optimization algorithm is disclosed for optimizing an implantable pulse generator. The algorithm is particularly useful when one or more of the electrodes (e.g., the case electrode) is used to provide a common mode voltage (Vcm) to the tissue, which assists in sensing neural responses to the stimulation. The algorithm preferably optimizes both the compliance voltage VH used to power the simulation circuitry, and the strength of tissue driver circuitry used to provide Vcm to the tissue. The algorithm preferably considers information determined by VH measurement circuitry (which informs as to the ability to form prescribed stimulation pulses without loading), sensing monitoring circuitry (which informs as to the magnitude of the inputs of the sensing circuitry), and/or tissue monitoring circuitry (which informs as to adequacy of the strength of the tissue driver circuitry).
