Layout Design of Low Power High Performance JK Flip-Flop with Modified Gate Diffusion Input Technique Using Cadence Virtuoso Tool for IC Design

The proposed work focuses on the layout design of a JK flip-flop aimed at achieving lower power consumption through the innovative application of the Gate Diffusion Input (GDI) technique. Leveraging Cadence Virtuoso as the primary tool, the project aims to demonstrate the efficacy of GDI in reducing power dissipation while maintaining the essential functionality of the flip-flop. The GDI technique involves utilizing a combination of simple logic gates to implement complex Boolean functions, thereby reducing the transistor count and, consequently, lowering power consumption. Through meticulous layout design and optimization, the paper explores various GDI configurations to minimize power dissipation in the JK flip-flop circuit. Key considerations include the selection of appropriate gate structures, transistor sizing, and interconnect routing to maximize the benefits of the GDI technique. Cadence Virtuoso provides a comprehensive platform for implementing these design choices, facilitating layout creation, simulation, and verification. The paper encompasses thorough simulation and characterization of the GDI-based JK flip-flop layout using Cadence Virtuoso Spectre. Performance metrics such as power consumption, speed, and area utilization are evaluated and compared with conventional flip-flop designs. The results demonstrate significant power savings achieved through the judicious application of the GDI technique, without compromising on key performance parameters. In conclusion, this work contributes to the advancement of low-power circuit design methodologies by showcasing the effectiveness of the GDI technique in reducing power consumption in JK flip-flop circuits.
