A standard cell circuit architecture and design is provided by way of this disclosure. The standard cell has a plurality of sub-cells that are designed to function together to generate a result and the plurality of sub-cells have at least one input. The standard cell further includes a protection device connected just before and to the at least one input of the plurality of sub-cells. The protection device is designed to prevent charge sharing with circuitry of another standard cell that may be electrically coupled to the standard cell by way of the at least one input. In a specific application of the standard cell, the standard cell can be designed to be a carry chain standard cell. The carry chain standard cell can then be incorporated as part of a library of cells that may be used by a software synthesis layout tool.
