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 mismatchinduced 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
