The document proposes a new circuit shared static flip-flop (CS2FF) for use in low-power digital VLSI systems. The CS2FF uses only 24 transistors, which is the same number as a conventional tri-state buffer based flip-flop. It operates by using five static NOR gates and two inverters to implement the master and slave latches. One NOR gate is shared between the master and slave latches to transfer data. Simulation results showed the CS2FF achieves stable operation at lower supply voltages compared to other flip-flop designs.
