Circuit diagram

Summary

A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations. The presentation of the interconnections between circuit components in the schematic diagram does not necessarily correspond to the physical arrangements in the finished device. Unlike a block diagram or layout diagram, a circuit diagram shows the actual electrical connections. A drawing meant to depict the physical arrangement of the wires and the components they connect is called artwork or layout, physical design, or wiring diagram. Circuit diagrams are used for the design (circuit design), construction (such as PCB layout), and maintenance of electrical and electronic equipment. In computer science, circuit diagrams are useful when vi

This course provides an overview of fundamental concepts of signal processing and electric circuits.

This course introduces the analysis and design of linear analog circuits based on operational amplifiers. A Laplace early approach is chosen to treat important concepts such as time and frequency responses, convolution, and filter design. The course is complemented with exercises and simulations.

Ce cours a pour objectif de former les étudiants de section Génie Electrique et Electronique à la conception de systèmes acoustiques, à l'aide d'un formalisme basé sur l'électrotechnique. A la fin du semestre, les étudiants seront capables de dimensionner, entre autres, des filtres acoustiques.

A new methodology for modeling minority carriers diffusion in Smart Power ICs substrate using standard circuit simulators has been proposed by EPFL. For this purpose, a parasitic substrate network consisting of lumped elements is extracted from the circuit layout following a given substrate meshing strategy. In this work Design of Experiments (DOE) techniques are used to run a limited number of simulations to evaluate the influence of the meshing on the accuracy of the EPFL Substrate Model when compared to finite element simulations. A two-dimensional case study on a parasitic lateral bipolar is then proposed with both spice-like and finite element simulation results for the minority carriers diffusion. A linear model is developed to estimate the most important geometrical domains influencing the accuracy of the studied model.

Fully automated parameter identification for synchronous machines.

Alexander Schwery, Jean-Jacques Simond, Mai Tu Xuan

The article presents a fully automated identification method for the determination of the sub-subtransient, subtransient and transient characteristic parameters of large synchronous machines. The software allows for an identification of the parameters based on the measurements of the terminal currents during a three-phase short-circuit as defined in the international standards. Based on the identified parameters the equivalent circuit diagram (ecd) is established and it can be used as model of the synchronous machine for numerical simulations to be performed later.

A circuit-level substrate current model for smart-power ICs

Maher Kayal, François Krummenacher, Fabrizio Lo Conte, Marc Pastre, Jean-Michel Sallese

This paper presents a new modeling methodology accounting for generation and propagation of minority carriers that can be used directly in circuit-level simulators in order to estimate coupled parasitic currents. The method is based on a new compact model of basic components (p-n junction and resistance) and takes into account minority carriers at the boundary. An equivalent circuit schematic of the substrate is built by identifying these basic elements in the substrate and interconnecting them. Parasitic effects such as bipolar or latch-up effects result from the continuity of minority carriers guaranteed by the components models. A structure similar to a half-bridge perturbing sensitive n-wells has been simulated. It is composed by four p-n junctions connected together by their common p-doped sides. The results are in good agreement with those obtained from physical device simulations. © 2010 IEEE.
