Quantum Dot Gate FET Based Multi-Value Logic Sequential Circuits

Abstract

The design of multi value logic sequential circuits based on QG-FET (Quantum dot Gate Field Effect Transistor) is discussed here. The QG-FET produces an intermediate state in between the two stable states(i.e.) ON & OFF, this is happening due to change in the threshold voltage over this range. The design of various sequential circuits using QDGFET which includes ternary D-flipflop and ternary right shift register is discussed. The proposed design of sequential circuits using QDGFET results an improved circuit parameter and less circuit elements in the implantation. The three state QG-FET will increase the bit handling capability of the device due to increase in number of states. So that, with less circuit elements at a time we can handle more number of bits.
