Researchers use constructs from the field of electrical engineering for the modelling and analysis of biological systems, but few exploit parallels between electrical and biological circuits for simulation purposes. The authors discuss the development of BioXyce, a circuit-based biological simulation platform that uses Xyce, a large-scale electrical circuit simulator, as its simulation engine. ...

In this paper, we propose a novel method to improve the circuit simulation accuracy of insulated-gate bipolar transistor (IGBT) power devices under short-circuit state. To determine IGBT junction temperature, transient thermal resistance an device on order micro seconds is estimated by simulations. The saturation current without self-heating effects based test and resistance. SPICE parameter ex...

Due to the expected increase of defects in circuits based on deep submicron technologies, reliability has become an important design criterion. Although different approaches have been developed to estimate reliability in digital circuits and some measuring concepts have been separately presented to reveal the quality of analog circuit reliability in the literature, there is a gap to estimate re...

In this paper, a voltage-current mode controller is proposed to adjust both the input current and DC voltage of a boost-inverter in order to improve the performance of the photovoltaic (PV). The proposed system is based on fuzzy-making-decision predictive voltage-current controller (FPVCC). The simulation results show that in case of using the proposed FPVCC, the input current of a PV array is ...

In this paper we address the chip-level thermal simulation problem. Our work is based on some early results treating electro-thermal problems on circuit level 11, 22. The developed electro-thermal simulation package has been integrated under Cadence DFWII Opus. Due to its relatively low CPU need this package can be used as a thermal veriication tool of layouts of analog circuits. In our approac...

In this paper a novel design of all-optical half-subtractor based on nonlinear directional coupler is proposed. By using four waveguides and appropriately adjusting the refractive indices and selecting the proper length of waveguides, halfsubtractor function can be obtained. The operation of this function is simulated by RSoft CAD-Layout (BeamPROP) simulator. The simulation results confirm the ...

Electromigration (EM) of the interconnects is a key factor in determining the reliability of an integrated circuit, especially for the present-day IC with shrinking interconnect dimension. The simulation of the EM reliability of the interconnects is usually performed using the line-via structure at the EM test temperature (e.g. 300 oC).However, such simulation using the line-via structure may n...

   This paper presents a novel design of quaternary logic gates using graphene nanoribbon field effect transistors (GNRFETs). GNRFETs are the alternative devices for digital circuit design due to their superior carrier-transport properties and potential for large-scale processing. In addition, Multiple-valued logic (MVL) is a promising alternative to the conventional binary logic design. Sa...
