Abstract: One of the mostly used circuits in the digital designs is Multiplier. In digital signal processing multiplication is the most commonly used function. Due to high throughput hardware multiplication is most commonly used. Many designs of multiplier have already been proposed for low power. GDI (Gate diffusion Input) a new technique for low power Multiplier design has a limitation of low output swing. Here a modified GDI cell based multiplier is designed and used for Low power and full output swing.
