PSP based DCG-FGT transistor model including characterization procedure

Abstract

A new DCG-FGT (Dual-Control-Gate Floating-Gate Transistor) transistor model for static and transient simulations is presented. The PSP MOS description is used as a basis for the formulation of the conduction channel behavior. The floating gate potential is implicitly computed with an added charge neutrality relation that ensures a good convergence. The model is running under electrical simulator (ELDO) and is characterized thanks to ICCAP software. It has been validated on an advanced STMicroelectronics technology. The final objective of this work is to provide an accurate and scalable model available in design framework.

On the Investigation of a Novel Dual-Control-Gate Floating Gate Transistor for VCO Applications

“…This transistor offers two operating modes leading to new approach in circuit design. The design flow has been completed by the extraction of compact model of DCG-FGT which is based on the PSP formulation [10]. This model has been calibrated with dummy cell implemented on STMicroelectronics 90nm FLASH technology.…”

“…It has been validated on 90nm FLASH technology from STMicroelectronics. An accurate and scalable model is available in design framework [10]. The DCG-FGT transistor has been implemented on a FLASH technology to get a uniform tunnel oxide (removal of thick oxide).…”

Study of comparison between the DCG-FGT and its equivalent circuit in MOS technology

“…The approach used to develop the DCG-FGT model [7] is based on the use of the charge neutrality approach coupled with a PSP formulation. The PSP is used to model the intrinsic transistor, which is connected, as illustrated Fig.3, between the drain, the bulk, the source and the floating gate nodes.…”
