In this work, a newly fabricated organic solar cell based on a composite of fullerene derivative [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) and regioregular poly (3-hexylthiophene) (P3HT) with an added interfacial layer of AgOx in between the PEDOT:PSS layer and the ITO layer is investigated and an equivalent circuit model is proposed for the device. Incorporation of the AgOx interfacial...

.Measurements o~ the high-frequ~ncy noi:e of a silicon double-injection diode result in (i'l)=a• 4kT ( 1/r) ~if With a= 1.04 and m agreement With the literature. A new interpretation demands Nyquist noise with a 121 in these devices at high frequencies. This is in accord with an equivalent circuit derived for the doubleinjection process. Speculations are made on the general validity of Nyquist ...

This paper presents equivalent circuit modeling of active planar reflectors which can be used for the detailed analysis and characterization of reflector performance in terms of lumped components. Equivalent circuit representation has been proposed for PIN diodes and liquid crystal based active planar reflectors designed within X-band frequency range. A very close agreement has been demonstrate...

The equivalent circuit concept derives from the Superposition Principle and Ohm’s Law. Two forms of the equivalent circuit, the Thévenin equivalent and the Norton equivalent, distill any linear circuit into a source and an impedance. The development of these equivalents spans almost seventyfive years, with others than the eponymous people assuming equally important roles. This report describes ...

Numerical simulation models for capacitive, micromechanical inertial sensors are presented. These dynamic, nonlinear models include the contributions of electrical, mechanical, and fluidic energy domains by means of electrical equivalent circuits consisting of lumped, frequency-independent components. The mechanical resonance modes, gap capacitances, gas film damping forces and the electrostati...

Rapid development of high frequency devices and IC technologies for wireless communication products created many opportunities and challenges in RF testing, packaging and modeling. In this paper we review these challenges and show trends in the test and modeling technologies to meet the demand. Different approaches for studying largesignal performance of high frequency circuits, incorporating w...

A hybrid translinear (TL) circuit constituted by two kinds of transistors, bipolar and CMOS transistors, was proposed to control its quiescent current. And a new method was introduced to analyze the hybrid TL circuit, which converted it into an uniform equivalent bipolar TL circuit. It simplified its analysis and design. This hybrid TL circuit is applied to the output stage of a class AB amplif...

Accurate and fast models of the equivalent circuit (EC) elements gapped multiwinding inductors are essential for design galvanically isolated converters, such as Flyback LLC converters. Typically, EC acquired from measurements or time-consuming FEM simulations, both which disadvantageous optimizing magnetic device. This paper proposes a device that exclusively uses impedance matrix elements, i....
