In Building 13 on MIT’s campus, there sits a half-a-million-dollar piece of equipment that looks like a long stretched-out chandelier, with a series of gold discs connected by thin silver pipes. The e...
Accurate Time Domain Method for Simulation of Microstructured Electromagnetic and Photonic Structures
Computational Electromagnetics Numerical Simulation Transmission Line Modeling
2010/2/2
A time-domain numerical model within the
framework of transmission line modeling (TLM) is developed to
simulate electromagnetic pulse propagation inside multiple
microcavities forming photonic crys...
An Accurate Method for Extracting the Critical Field in Short Channel NMOS Devices
Drain saturation voltage Critical field Substrate current Effective mobility
2010/12/8
In this letter, an accurate method for extracting the critical field Ec in short channel MOSFET's is presented. The principle of this method is based on the comparison between two models which give dr...
Economical and Accurate Digitally Programmable Dual-Polarity Gain Amplifier
Dual-Polarity Gain Amplifier switches
2010/12/14
A digitally programmable, dual-polarity gain amplifier is proposed. It uses total resistance less than those presented earlier. The effect of on-resistance of switches can be fully compensated.
Accurate Single-Section Model of Mosfet Including Substrate Resistivity
Mosfet Substrate Resistivity
2010/12/16
Practical MOSFETS fabricated on low and moderately doped substrates depart
considerably from the idealized two-port model because of the control properties
of the substrate terminal. Therefore, the ...
