| Abstract: | With the on-going improvement of integrated circuit technology, there are more and more resources with the on-chip interconnection. By studying the capacitive coupling model between lines, in this paper a design scheme of SR latch circuit is proposed based on interconnected capacitance coupling. Capacitance coupling relationship between interconnected lines is established using MOS gate capacitance to simulate interconnected capacitance, and then using capacitive coupling structure and line calculation characteristics. Through designing or NOR gate, SR is implemented based on interconnected capacitance coupling latch circuit. Finally, the simulation is conducted to verify the proposed design in the TSMC 65nm Spectre environment. The results show that the designed circuit logic function is valid and has low hardware overheads. |
