The quasi-2D method has been used to account for short-channel effects in PN-junction MOSFETs. Recently some authors applied the quasi-2D solution to SB MOSFETs to derive potential profiles. In this paper, an improved quasi-2D solution is proposed which is valid for arbitrary terminal bias with respective to any reference voltage and applicable to asymmetric SB-DG devices. A terminal-bias dependent characteristic length is physically derived, which has been missed in all previous literature.
