A　charge　balancing　technique　that　is　applicable　to　dual-edge　current　nerve　stimulators　is　proposed　herein,　which　is　primarily　directed　to　achieving　charge　balance　by　controlling　discharge　times.　Compared　to　the　charge　balancing　technique　proposed　in　other　papers,　the　number　of　single-cycle　imbalanced　charges　is　less　than　15　pC.　In　order　to　reduce　the　amount　of　imbalanced　charge,　indirect　shunt　technology,　leakage　current　compensation　technology　and　offset　voltage　compensation　technology　was　proposed　in　this　paper　to　build　up　a　synchronization　system.　To　ensure　that　the　neural　stimulator　can　still　be　in　charge　balance　after　performing　multiple　stimulation　cycles,　a　short　pulse　insertion　technique　is　applied　to　the　circuit.　The　circuit　was　designed　based　on　the　TSMC　180　nm　process　and　verified　its　functionality　under　the　Cadence　platform.
