Abstract
In this paper, we analyze faradaic DC current (FC) generated by inherent offset charge (IOC) and charge mismatch. Under frequent shorting, the analysis shows that mismatch-induced DC current is small compared to IOC-induced DC current. To reduce the FC, we propose a biphasic pulse scheme which compensates the IOC. Simulation results show the proposed pulse scheme reduces the FC by about 58 times compared to a conventional biphasic pulse.
