Ternary Logic Flip-Flops Using Quantum Dot Gate Field Effect Transistor (QDGFET)

In this paper, ternary logic SR, JK and D Flip-Flops using three-state quantum dot gate field effect transistors are introduced. Due to the change in the threshold voltage, Quantum dot gate field effect transistors (QDGFETs) produce an intermediate state between the on and the off state of the device. The author has developed a simplified circuit model that accounts for this intermediate state. Interesting logic can be implemented using quantum dot gate field effect transistors. In this work, designs of different Flip-Flops in ternary logic using QDGFET based ternary NAND and ternary NOR have been discussed. More states in the QDGFET increase the bit handling capabilities of this device and help us to design complex circuits with fewer circuit elements.
