Generalization of a circuit theory for current perpendicular to plane magnetoresistance and current-driven torque

Physical Review B, 2006
Extensions of an existing circuit theory for current perpendicular to plane magnetoresistance and current-driven torque in noncollinear magnetic-multilayer pillar devices are presented. Our expressions for monodomain critical-current threshold ${J}_{c}$ and giant magnetoresistance $\mathrm{\ensuremath{\Delta}}R$ are firstly derived in terms of assumed ...

The general fluid circuit theory of active chloride absorption

The Bulletin of Mathematical Biophysics, 1940
The original fluid circuit theory used to explain active intestinal absorption of chloride is modified to include diffusion and secretion of chloride and osmosis. The general differential equation developed is integrated in a particular case. The definition, “effective concentration of chloride in the fluid passing into the intestinal lumen,” leads to ...

Correlation Between the Theory of Lissajous Figures and the Generation of Pinched Hysteresis Loops in Nonlinear Circuits

IEEE Transactions on Circuits and Systems I: Regular Papers, 2019
In this paper, the application of the theory of Lissajous figures to the creation of pinched hysteresis loops, considered to be a characteristic of memristive systems, is demonstrated and experimentally verified using designed electronic circuits in the form of an input impedance.

A novel high speed Artificial Neural Network–based chaotic True Random Number Generator on Field Programmable Gate Array

International journal of circuit theory and applications, 2018
It is well observed that cryptographic applications have great challenges in guaranteeing high security as well as high throughput. Artificial neural network (ANN)–based chaotic true random number generator (TRNG) structure has not been unprecedented in ...

General theory of multi-leg power conversion circuits based on neutral point voltage

ISIE'2000. Proceedings of the 2000 IEEE International Symposium on Industrial Electronics (Cat. No.00TH8543), 2002
This paper describes the general theory of the main circuit constructions and control methods of legs based on output neutral point voltage control under multi-leg power conversion circuits. A controllable fluctuation range of the output neutral point voltage is obtained by the linear programming method under the condition of the desired symmetrical ...

An improved FDTD formulation for general linear lumped microwave circuits based on matrix theory

IEEE Transactions on Microwave Theory and Techniques, 2005
An improved finite-difference time-domain (FDTD) formulation using the matrix theory is presented to analyze hybrid general linear lumped and distribution microwave circuits. Traditionally, since discrete current expressions of lumped circuits should be substituted into Maxwell's equations explicitly, the different discrete formulations of Maxwell's ...

A general theory of third-order intermodulation distortion in common-emitter radio frequency circuits

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
This paper presents a general analysis of the 3rd-order nonlinearity of a single-ended and differential common-emitter (CE) radio frequency (RF) amplifier. With direct computation of the third-order nonlinear response, a closed-form expression was derived. The results suggested several novel ways to cancel the third-order nonlinearity without affecting

New approach to general theory of electrical machines using magnetic equivalent circuits

Proceedings of the Institution of Electrical Engineers, 1973
First, the nature of equivalent circuits and the alternative electric or magnetic equivalents for any electromagnetic system are examined. In the remaining Sections, steady-state and symmetrical sudden short-circuit conditons are analysed for the3-phase synchronous, the 3-phase induction and the compounded d.c.

Generalized theory of instantaneous active and reactive powers in single-phase circuits based on Hilbert transform

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
This paper presents a new theory of instantaneous power in single-phase circuits, which is named "ps-qs theory". The ps-qs theory is formed based on the Hilbert transform and allows us to define the active and reactive powers instantaneously in single-phase circuits that operate in transient state.

SELF-CONSISTENT FIELD THEORY OF GENERAL PERIODIC CIRCUITS FOR TRAVELING WAVE TUBES

International Journal of High Speed Electronics and Systems, 1993
A general method for exact analysis of cylindrical periodic circuits for traveling wave tubes without initial assumptions of field or current distributions is described. The procedure is based on transforming the stationary periodic circuit to Fourier space, in the same manner as one does the ordinary RF fields.
