A Single-Device Embodiment of XNOR Logic: TransiXNOR

In most digital circuits and systems, transistors are engineered only for simple switching. Much recent research has focused on developing novel transistors as efficient switches [1]. On the other hand, a single transistor can also be designed to achieve richer functionalities. By taking advantage of the ambipolar behavior of tunnel field-effect transistors (TFETs), in this paper we propose a device concept, TransiXNOR, which is a dual-gate four-terminal transistor implementing XNOR logic within a single device.
