AC Equivalent Circuit Modeling
2001Converter systems invariably require feedback. For example, in a typical dc-dc converter application, the output voltage v(t) must be kept constant, regardless of changes in the input voltage v g (t) or in the effective load resistance R. This is accomplished by building a circuit that varies the converter control input [i.e., the duty cycle d(t)] in ...

Equivalent circuit modeling of coupled resonator filters
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2008Using the stacked crystal filter (SCF) concept, a coupled resonator filter (CRF) can be interpreted as a device in which 2 piezoresonators are stacked on top of each other in such a way that a certain degree of acoustic interaction occurs. The work presented in this paper reports a novel all-electrical model for the CRF. The model associates acoustical

An equivalent-circuit radiation sensor model
Proceedings of SOUTHEASTCON '94, 2002The utility of pyroelectric detectors at infrared and visible light frequencies is common knowledge. However, it is not well known that pulsed or otherwise amplitude modulated microwave radiation also can be detected with pyroelectric materials.

Equivalent circuit model of UTC photodiode
2012 5th International Conference on Computers and Devices for Communication (CODEC), 2012In this work we have examined different characteristics of uni travelling carrier (UTC) photodiode (PD) by mathematical modeling of the device. Based on the basic circuit elements contain in the mathematical model, an equivalent circuit model of UTC-PD is developed.

1993
During the last decade, there has been a shift in emphasis in device modelling research away from equivalent circuits and in favour of numerical device simulation. This has been driven by a rapid increase in the computing power to cost ratio and the assertion that the solution of the fundamental device equations is required to adequately model modern ...

1999
The following sections discuss creating equivalent circuit models of packages from measured data and creating models from EM simulation results. Assuming we can do both well, it is usually best to choose measurement where a physical part and appropriate test board already exist. EM simulation’s big advantage is simulating structures that do not already

New equivalent circuit model for HEMT
1999 Asia Pacific Microwave Conference. APMC'99. Microwaves Enter the 21st Century. Conference Proceedings (Cat. No.99TH8473), 2003AC I-V behavior between the terminals of a HEMT are investigated experimentally from several hundred Hz to 1 MHz. The results show that the AC I-V characteristics among the terminals, such as drain-source, gate-source, and gate drain, are the same as those of an LC tank, thus, a new equivalent circuit model in the AC frequency range is proposed based ...

An equivalent circuit model for IGBT
Proceedings of the 2000 Third IEEE International Caracas Conference on Devices, Circuits and Systems (Cat. No.00TH8474), 2002A new circuit model for the IGBT is developed. This model uses the transmission-line circuit technique and is suitable for circuit simulators. The new circuit model for the IGBT is implemented into widely used SPICE3 and all the simulation results are compared with the results of the TMA MEDICI device simulator.

Equivalent-Circuit Modelling of Chassis Radiator
2009 German Microwave Conference, 2009The comparison of the characteristics of a flat dipole and the rectangular chassis eigen-mode leads to the concept of the chassis radiator as a flat dipole with completely filled, short-circuited terminal area. The equivalent circuit for the chassis radiator is derived from the flat dipole equivalent circuit by exclusion of the parasitic feed inductor ...
