Compact Unipolar XNOR/XOR Circuit Using Multimodal Thin-Film Transistors

A novel compact realization of the XNOR/ XOR function is demonstrated with multimodal transistors (MMTs). The multimodal thin-film transistors (MMT’s) structure allows efficient use of layout area in an implementation optimized for unipolar thin-film transistor (TFT) technologies, which may serve as a multipurpose element for conventional and emerging large-area electronics. Microcrystalline silicon device fabrication is complemented by physical simulations.
