Abstract
A method and system for charge imbalance compensation in a stimulating medical device is provided. The stimulating medical device includes at least one electrode contact configured for providing stimulation to a recipient. A charge imbalance compensation system in the stimulating medical device measures any residual charge remaining on the electrode contact that may result from an imbalance in the applied stimulation. If the measured residual charge exceeds a threshold, the charge imbalance compensation system causes a compensator current to be applied to reduce the residual charge. This residual charge may be measured by measuring a potential difference between the electrode contact and a reference electrode; or, by measuring a potential difference across a capacitor in-series with the electrode contact.
