Small signal modeling of illuminated MOSFET for RF application

Proceedings of the International Conference & Workshop on Emerging Trends in Technology, 2011
Recent development in the device technology has led to the potential research in the area of optical characterization of FET devices. It is mainly because of the high gain, speed, power handling capacity and high packing density of IC viz. OEIC, MMIC, VLSI, etc.

Small Signal Modeling of Full Bridge Boost Converter

2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019
In this paper, a small signal model for full bridge boost converters is derived by using state space averaging method. The converter is extensively used for integration of renewable resources such as PV panels. The obtained model can be used for designing linear control systems for regulating the converter’s current or voltage.

Small Signal Model Averaging of Bi-Directional Converter

2018 IEEE International Conference on Electro/Information Technology (EIT), 2018
We consider the problem of modeling a bi-directional AC/DC converter using a small signal approach coupled with cycle averaging to simplify the model for use in digitized control. Small power sources (≤ 1000W) tend to have more abrupt transient power flow due to the associated characteristic low inertia. This is prevalent in small wind turbine systems.

On small signal equivalent circuit models for quantum dots

International Journal of Circuit Theory and Applications, 2017
SummaryIn this paper, we introduce small signal equivalent circuit models for quantum dots at equilibrium driven by classical electromagnetic fields. We investigate both an isolated quantum dot and a pair of interacting quantum dots coupled by the electric dipole–dipole interaction.

FET Small Signal Modeling and Parameter

2010
In this chapter, we introduce small-signal modeling and parameter extraction technique for FETs, an III-V compound semiconductor device pseudomorphic high electron-mobility transistor (PHEMT) is used as an example. The parameter extraction includes pad capacitances, extrinsic inductances, extrinsic resistances, and intrinsic elements extractions.

Three-phase photovoltaic inverter small-signal modelling and model verification

6th IET International Conference on Power Electronics, Machines and Drives (PEMD 2012), 2012
The number of power electronic converters is increasing in the grid due to favourable political climates regarding renewable energy resources. Grid-parallel inverters have been shown to suffer from reliability problems that may not be solved with pure time domain analysis.

Small signal model for low power DSP

1995 IEEE Symposium on Low Power Electronics. Digest of Technical Papers, 2002
We describe a technique which reduces power consumption in pipelined DSP circuits by mapping full precision operations to small precision operations, using adaptive delta modulation to reduce the signal size. The discrete cosine transform example is evaluated considering issues such as power, area, delay, latency, accuracy of the system and the ...

A comparision of small signal homojunction and heterojunction model

ASDAM '98. Conference Proceedings. Second International Conference on Advanced Semiconductor Devices and Microsystems (Cat. No.98EX172), 2002
The N-AlGaAs/p-GaAs heterojunction with dc bias and small ac signal is investigated. It is shown that its complex small signal admittance consists of two contributions; the first one is the minority electron diffusion in quasineutral p-region region and the second one is the process of thermionic emission at the abrupt heterointerface.

Small-Signal Modeling of Resonant Converters

2011
Resonant DC-DC converters play an important role in applications that operate at high-frequencies (HF). Their advantages over those of pulse-width modulated (PWM) DC-DC converters have led to the invention of several topologies over the traditional forms of these converters. Series resonant converter is the subject of study in this thesis. By variation
