Abstract
There is described an electrical tissue stimulating device, such as a cochlear prosthesis, which includes circuitry (,) for monitoring the build-up of undesirable residual voltages between stimulation electrodes. In the event that such a condition is sensed then an overvoltage signal is generated and transmitted to a switch controller (,). In response the switch controller controls electrode switches (,) in order to suppress stimulation of the monitored electrode(s) until the undesirable residual voltage has fallen to an acceptable level. As a result the build-up of undesirable inter-electrode voltages is reduced.
