We present results from fully two-dimensional physical device simulation. Scattering parameters (S-parameters) are directly obtained from small-signal AC-analysis of real heterostructure devices. A comparison reveals very good agreement with measured data.

This paper presents small signal stability study carried over the 140-Bus, 31-Machine, 5-Area MEPE system and validated on free and open source software: PSAT. Well-established linearalgebra analysis, eigenvalue analysis, is employed to determine the small signal dynamic behavior of test system. The aspects of local and interarea oscillations which may affect the operation and behavior of power...

This paper gives an introduction to phasors and AC small-signal analysis with an emphasis on demonstrating how one can quickly understand the behavior of simple AC circuits without detailed calculations by examining the circuit and using high level reasoning.

A novel technique for the numerical extraction of equivalent circuits from physics-based device simulation is presented. The method is based on the partitioning of the device into functional regions, each corresponding to a circuit block. All the circuit elements have a clear physical interpretation. Element values are directly obtained from small-signal dc device simulation. The method generat...

A CMOS operational amplifier with input/output rail-to-rail range is presented. The circuit operates with a 1-V single supply. It uses dynamically biased input level shifters, controlled by a novel tuning scheme, to extend the input common-mode voltage range from one rail to the other. The tuning circuit takes the total biasing current of the amplifier input stage and, hence, its small-signal r...

We present the photoproduction of an intermediate mass Higgs (IMH) boson associated with a W boson at the future electron-proton colliders using bremsstrahlung photon beam or laser backscattered photon beam. With bremsstrahlung photon beam the search for the IMH boson is unfavorable because of the small signal rate. But with laser photon beam the search is viable due to a much larger rate, and ...

We analyze the prospect for observing the intermediate neutral Higgs (h2) boson in its decay to two lighter Higgs bosons (h1) at the Tevatron in the framework of the CP violating MSSM using the PYTHIA event generator. We consider the lepton+ 4-jets+ E/T channel from pp̄ → W h2 → W h1h1 → lνlbb̄bb̄, with two or three tagged b jets. We found that it is very hard to observe this signature in the LEP-...

Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

The paper investigates the small-signal stability of a 270V DC power system for a more electric aircraft, which employs switched reluctance generator technology and multiple distributed power electronic converters for flight control surface actuation, environmental control, and numerous DC and AC loads. Non-linear state space models for the complete system have been established and the eigenval...
