Abstract

In this paper, we propose the implementation of XNOR logic operation within a single positive feedback (PF) device using a novel scheme. The PF operation based on the floating body effect and band-to-band tunneling (BTBT) phenomenon was experimentally observed and further analyzed through TCAD simulation. By fixing VG1, the output logic state can be controlled by dividing the VG2 range into distinct regions corresponding to logic '0' and '1'. These results suggest a promising pathway toward miniaturization and high-density integration of logic circuits, with potential applicability to the design of next-generation digital computing architectures.
