Compact Modeling of Emerging Technologies with VHDL-AMS
نویسندگان
چکیده
This paper deals with the compact modeling of several emerging technologies: first, the double-gate MOSFET (DG MOSFET), and second, the carbon nanotube field-effect transistor (CNTFET). For CNTFETs, we propose two compact models, the first one with a classical behavior (like MOSFET), and the second one with an ambipolar behavior (Schottky-barrier CNTFET). All the models have been compared with numerical simulations and then implemented in VHDL-AMS.

Behavioral Modeling and Simulation of Semiconductor Devices and Circuits Using VHDL-AMS
During the past few years, a lot of work has been done on behavioral models and simulation tools. But a need for modeling strategy still remains. The VHDL-AMS language supports the description of analog electronic circuits using Ordinary Differential Algebraic Equations (ODAEs), in addition to its support for describing discrete-event systems. For VHDL-AMS to be useful to the analog design ...
متن کاملModelling single-electron tunnelling circuits in VHDL-AMS
Abstract The single-electron tunnelling (SET) devices might be scaled down almost to the molecular level. SET devices can be faster and consume less power than comparable devices implemented in CMOS or bipolar technologies. This work presents VHDL-AMS macro-modelling techniques for the compact simulation of single-electron circuits. The macromodel of the single electron transistor, which is muc...
متن کاملAnalyzing Performance of VHDL-AMS for Switch Level Modeling and Simulation
VHDL-AMS (IEEE 1076.1-1999), an extension to the VHDL, is considered to be a unified language for digital analog, mixed-signal modeling [1],[2]. Although traditionally AMS language is commonly used for behavioral modeling, in this paper special emphasis is given to modeling of mosfet based devices at switch level. We have analyzed VHDL-AMS for switch level modeling on basis of accuracy and resp...

In this paper we present a family of Mixed-signal (mixed analog/digital) synthesis tools being developed at the University of Cincinnati. The VASE (VHDL-AMS Synthesis Environment) project involves the development of a vertically integrated synthesis environment centered around the emerging VHDL-AMS standard for specification of analog and mixed signal systems. The unique contributions of this r...
