Any of several types of steel used for manufacturing the magnetic field components of machines and transformers. electrical substation A facility connecting a distribution network to a transmission network, usually with one or more transformers. electrical technologist A specialist in applying electrical theory and technique to practical problems.
Therefore, circuit simulators normally use more empirical models (often called compact models) that do not directly model the underlying physics. For example, inversion-layer mobility modeling , or the modeling of mobility and its dependence on physical parameters, ambient and operating conditions is an important topic both for TCAD (technology ...
integrated circuit (IC) – a miniature electronic circuit formed by microfabrication on semiconducting material, performing the same function as a larger circuit made from discrete components interconnect (n.) – wires or signal traces that carry electrical signals between the elements in an electronic device
Microfabrication is actually a collection of technologies which are utilized in making microdevices. Some of them have very old origins, not connected to manufacturing, like lithography or etching. Polishing was borrowed from optics manufacturing, and many of the vacuum techniques come from 19th century physics research.
Printed circuit board Electrical Circuit with an IC. Electronic engineering is a sub-discipline of electrical engineering that emerged in the early 20th century and is distinguished by the additional use of active components such as semiconductor devices to amplify and control electric current flow. Previously electrical engineering only used ...
An Integrated circuit (IC) as an example application in the field of microelectronics. The chip housing is opened to allow a view of the actual circuit. The golden connecting cables, which form the electrical wiring between the IC and the housing contacts, can be seen on the sides. Microelectronics is a subfield of electronics.
An electronic circuit can usually be categorized as an analog circuit, a digital circuit, or a mixed-signal circuit (a combination of analog circuits and digital circuits). The most widely used semiconductor device in electronic circuits is the MOSFET (metal–oxide–semiconductor field-effect transistor). [3]
The International Electrotechnical Vocabulary (IEV) is managed list of terms and definitions organized by the International Electrotechnical Commission (IEC), which is grouped in classes. It serves to promote the global unification of terminology in the field of electrotechnology, electronics and telecommunications.
