Design and Analysis of Low Power High Speed Hybrid Alternative Full Adder Circuits

Shreedevi ^[2] | Taranath H. B

Abstract: This project deals with designs of 1-bit hybrid alternative full adder using complementary metal-oxide-semiconductor (CMOS) logic, gate diffusion input (GDI) technique, modified GDI and transmission gate logic are reported. These designs are implemented using Mentor graphics tool. The power dissipation and transistor count is compared to the other hybrid adder designs and the existing designs such as complementary pass-transistor logic, transmission gate adder and hybrid pass-logic with static CMOS output drive full adder, mixed topology of GDI (Gate diffusion Input) technique with both inverter and mirror adder so on. This design is divided into three modules and found to working efficiently with less power dissipation and transistor count at 180nm technology.
