This paper presents analysis and simulation of a CMOS based cortical neuron circuit at 0.25μm technology node. The spiking and bursting patterns generated after the simulation of the circuit are studied. Also, the effect of variation of the (W/L) ratios of transistors on the spiking pattern is analyzed in this paper. The results obtained by simulation and the variations in parameters shows that...

In this paper, a Y-shaped power splitter based on a two dimensional photonic crystal (PhC) for TE modes is designed and optimized. A triangular lattice of air holes is used for Y-shaped power divider. For analyzing these structures, plane wave expansion (PWE) and finite difference time domain (FDTD) methods are used. The simulation results show that more than 98% of the input power is transmitt...

Multiple coupled circuit modeling (MCCM) of squirrel-cage induction motors (SCIMs), or winding function approach is the most detailed and complete analytical model used to analyze the performance of faulty SCIMs. Already, in variate papers this approach was used to 3phases SCIMs, but this paper extends the above-mentioned model to 6phases SCIMs. Various simulations of variative faults are carri...

   In this paper we propose a simulation study to carry out dynamic analysis of CNTFET-based digital circuit, introducing in the semi-empirical compact model for CNTFETs, already proposed by us, both the quantum capacitance effects and the sub-threshold currents. To verify the validity of the obtained results, a comparison with Wong model was carried out. Our mode...

Coplanar wave guide (CPW) inter digital capacitor (IDC) configurations on printed circuit board (PCB) and parametric variations over frequency are studied by simulation using ADS Momentum. The structures are fabricated in printed circuit board using PCB fabrication techniques. The scattering parameters of the structure are measured using vector network analyzer (VNA). The capacitance is estimat...

Analog synthesis tools have traditionally traded quality for speed, substituting simplified circuit evaluation methods for full simulation in order to accelerate the numerical search for solution candidates. As a result, these tools have failed to migrate into mainstream use primarily because of difficulties in reconciling the simplified models required for synthesis with the industrial-strengt...

-The numerical calibration and de-embedding techniques used in the planar electromagnetic (EM) simulation are reviewed. These techniques are used to eliminate the port discontinuities brought by the current/voltage exciting source. Therefore, accurate equivalent circuit model of the planar discontinuities can be extracted. Index Terms – calibration technique, equivalent circuit model, planar di...

A CAD environment leading from technology to performance evaluation by integrating process, device, and circuit simulation would be a valuable tool for the development of monolithic microwave circuits. The paper focuses on the linkage between a physical device simulator for smalland large-signal characterization, and CAD tools for both linear and nonlinear circuit analysis and design. Efficient...
