Qualitative analysis of an equivalent full adder circuit using MIGFET: An alternative approach to full adder circuit via direct truth table implementation

A Multiple Independent Gate Field Transistor (MIGFET) has more than one gates. These gates may be placed on or around the channel. An advantage of multiple gates structure is the better control of the channel region than the single gate structure. Another use of multiple gates can be to the increase functionality per transistor. In this paper, we present a functionally equivalent full adder circuit using the MIGFET structure that is feasible and more advantageous in many respects. We also show a simple improvement of the equivalent circuit. This technique of MIGFET implementation of digital logics can be extended to other digital logic circuits as well.
