spiceis a widely used simulation tool for electrical circuits and systems. When optoelectronic elements, such as lasers, detectors, modulators, etc., and optical elements, such as lenses, gratings, beam splitters, etc., are incorporated into spice, optoelectronic system simulation can be combined with that of electronic systems, facilitating hybrid system design and analysis. We discuss an opto...

This paper proposes a SPICE model development methodology for quantum-dot cellular automata (QCA) cells and presents a SPICE model for QCA cells. The model is validated by simulating the basic logic gates such as inverter and majority voter. The proposed model makes it possible to design and simulate QCA combinational circuits and hybrid circuits of QCA and other NANO devices using SPICE. In th...

cinnamon plant, especially its peel, is one of the considerable spices for its using as drug, spice and freshener from ancient times. distribution of different kinds of cinnamon is in some regions of eastern and southern asia and it has been traded to other countries. but because of the importance and high price of this spice, its history has been mixed with tales and superstitions. this articl...

A SPICE model for the microwave and RF PIN switching diode is presented. The model simulates the important Iregion charge storage phenomenon and its effect on the PIN diode impedance-frequency characteristic. The SPICE model is described and validated by comparisons with both analytical and measured results.

This paper proposes to study the performance of carbon nanotube bundle in terms of delay as a VLSI interconnect at 32nm technology node. Output waveform and 90% propagation delay are analytically determined and compared with SPICE simulation result. Alpha power law model is used for representing the transistors of CMOS driver. SPICE simulation result reveals that delay increases with increase i...

A SPICE-compatible simulation methodology for analyzing open– and closed-loop high-frequency electronic ballasts for fluorescent lamp was developed. The proposed procedure applies envelope simulation and makes use of the SPICE-compatible model of a fluorescent lamp. Experimental results validate the reliability of proposed simulation method.

Process Improvement has been used for decades as a means to become better and more efficient. Whilst many organizations have used considerable resources for process improvement, investments in process improvement have not always led to changes and improvements expected. One most important aspects of management is to motivate the work force. However, management often fails to deliver. In fact, b...
