This paper presents a Matlab toolbox for the symbolic analysis and simulation of linear analog circuits. The simulator uses Modified Nodal Analysis (MNA) method to solve linear networks in the s-domain and exploits the Symbolic Math Toolbox for post-processing and numerical simulation. Starting from a SPICE-like netlist, the tool evaluates the circuit node voltages and the current in each independent...
This paper presents a performance evaluation procedure for an inductive wireless power transfer (WPT) system with a parallel-parallel compensation network. The effect of the WPT system design parameters on its efficiency is investigated. The WPT system is modeled using a 3D electromagnetic field technique coupled with circuit simulation. The 3D finite element (3DFE) model is created and a MATLAB-FEA...
This paper describes a new technique to simulate MATLAB system models in PSpice environment. The algorithmic component of the design is developed using MATLAB, and then exported to a C-model which can be read and simulated by PSpice using its newly developed PSpice Device Modeling Interface (DMI). The paper describes in detail the changes required to make the MATLAB C-Model compatible with PSpice...
The NEEDS initiative has a mission to provide physics-based, SPICE-compatible compact models for emerging nano-devices. NEEDS is also developing a complete compact model development toolset, complemented with educational and training resources. NEEDS-developed resources are disseminated at needs.nanohub.org. The overall goal is to connect research in materials and devices to circuit and system level...
This paper proposes a method to recast the classic circuit simulation algorithm to maximize parallelism by formulating the circuit equations as state variable equations and using an integration method such as Runge Kutta as the foundation to break the time dependencies. A brief introduction to the SPICE algorithm and previous attempts to exploit parallelism is given. The implementation of the new...

An envelope method of RFIC simulation is mainly discussed in the paper. In the method, the slowly varying envelope components are for transient analysis of SPICE. On each time point of the transient analysis, fast pulse response is calculated by the harmonic balance method, and relatively insensitive to the rate of the high frequency carrier. The method could be used to efficiently simulate the transient...
For FPGA-based three level switching power amplifier, this paper completed full-bridge circuit model and the current sampling circuit model was created by using Power System Blockset (PSB) library in the MATALB/Simulink. Through embedded MATLAB function file, we simulated the internal FPGA data processing. Simulation and experimental results verified the correctness of this method of modeling. And...
Students usually asked to accomplish some experiments during the specialized courses learning in electron information specialty. Students have blindness when they first contact the experiments because of the complexity of the circuit, so this usually leads to the damage to the experiment device. Therefore, it is necessary to make the students to know the theory, models and adjustable parameters of...
The development of systems implementing renewable energy sources is essential to society's evolution and survival. Currently the major source for electric energy is the burning of fossil fuels; thus, it is a problem because of two reasons: it increases the emission of harmful gases to our atmosphere and it is an energy source that will not last forever. In our present time the amount of energy produced...

An extension to a formal verification approach of hybrid systems is proposed to verify analog and mixed signal (AMS) designs. AMS designs can be formally modeled as hybrid systems and therefore lend themselves to the formal analysis and verification techniques applied to hybrid systems. The proposed approach employs simulation traces obtained from an actual design implementation of AMS circuit blocks...
