Abstract

In designing ALUs, many techniques have been followed. The functional units of an ALU have been realized using conventional transistors and pass transistor gates. In this paper, we present the design of a 4 bit ALU using multi-input floating gate (MIFG) CMOS reconfigurable logic. It has been designed in a 1.5 μm technology for 3 V operation. The ALU can perform four arithmetic and four logical operations. The core of the ALU, which is a full adder circuit, has been realized using MIFG transistors. Additional logic gates have also been built using MIFG transistors. The design we present is simple in structure with significantly lesser number of transistors and interconnections when compared to earlier designs.
