A wide-band physical and scalable 2equivalent circuit model for on-chip spiral inductors is developed. Based on physical derivation and circuit theory, closed-form formulas are generated to calculate the RLC circuit elements directly from the inductor layout. The 2model accurately captures ( ) and ( ) characteristics beyond the self-resonant frequency. Using frequency-independent RLC elements, ...

We developed a hands-on laboratory exercise for undergraduate students in which they can build and manipulate a neuron equivalent circuit. This exercise uses electrical circuit components that resemble neuron components and are easy to construct. We describe the methods for creating the equivalent circuit and how to observe different neuron properties through altering the structure of the equiv...

BACKGROUND The switching exercise (e.g., Interval Training) has been a commonly used exercise protocol nowadays for the enhancement of exerciser's cardiovascular fitness. The current difficulty for simulating human onset and offset exercise responses regarding the switching exercise is to ensure the continuity of the outputs during onset-offset switching, as well as to accommodate the exercise ...

abstract this study is an attempt to investigate the influence of targeting subsidies on price transmission pattern in iran's egg market. the targeting subsidies plan was imposed by 20 december 2010. using of daily price time series data, the study was conducted during december 2009 to october 2011. using ecm model, price transmission models were estimated for the two periods (e.g. before and a...

An equivalent circuit model of coaxial probes is derived directly from the intrinsic via circuit model. As all the higher-order evanescent modes have been included analytically in the parasitic circuit elements, only the propagating mode needs to be considered by the simplest uniform-current model of a coaxial probe in numerical solvers such as finite element method (FEM) or finite difference t...

Modeling a MEMS (Micro Electro-Mechanical Systems) electrostatic actuator in electrical domain is important for system simulation of the actuator along with its associated electronics. For instance, an integrated MEMS resonator used in a serial I/O PLL design modeled in electrical domain enables to optimize the system with the rest of the electronics. In this work, we have developed a simplifie...

This article focuses on the electric modeling of split ring resonators with a new approach based on an equivalent circuit. The elements of circuit are determined from geometric parameters forming the three dimensional model of this type of resonators. In the first part, an analytic study is proposed about the determination of the components of the circuit according to a function of physical par...
