Abstract
An implanted device such as cochlear implant having electrodes is provided with a pulse generator for generating stimulating pulses. The pulses are adjusted to insure that during the idle periods between the pulses, the voltage on the electrodes is at zero or at a preselected level. In one embodiment, the pulse durations or amplitudes adjusted, In another embodiment the voltage on the electrodes is measured before and during each pulse to determine IR drops from the electrodes to a reference point, and to compensate for the same.
