An analysis of faradaic DC current generated by inherent offset charge (IOC) and charge mismatch is suggested. Under frequent shorting, this analysis shows that mismatch-induced DC current is trivial compared to IOC-induced DC current, and it is also verified by simulation. An advanced biphasic pulse which compensates the IOC is suggested. Simulation results show the advanced pulse reduces the FC by about 58 times compared to a conventional biphasic pulse.
