▎ 摘　　要

NOVELTY - The method involves forming a MOSFET with graphene material. The MOSFET is formed in an active region area. The active region area is formed with a source leakage metal contact. Stop frequency of the MOSFET is detected. A contact capacitor is connected between a small signal module and the active region area. A Fresnel-Kirchhoff current law (KCL) and Kirchhoff voltage law (KVL) analysis method is used to obtain cut-off frequency of the MOSFET, and a feedback modification small signal equivalent model is established. USE - Method for calculating cut-off frequency of a small signal model of a graphene transistor. ADVANTAGE - The method enables performing small signal model graphene transistor cut-off frequency calculating process in reasonable, simple and easy manner with better accuracy. DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for calculating cut-off frequency of a small signal model of a graphene transistor.
