Abstract
Charge balancing is a major concern in functional electrical stimulation. Any excess charge accumulation over time leads to electrolysis with the electrode dissolution and tissue destruction. Therefore, charge balance circuits are used for mitigating the effects of charge accumulation in tissues. This work introduces an active synchronous charge balance circuit for constant current neural stimulators that operates without requiring negative supply for remaining charge detection. The charge balance circuit detects the residual charge by monitoring the electrode voltages just before the stimulation. If the voltage difference between the electrodes is above a certa...
