Basic Laws and Analytical Methods for Circuit Analysis
Circuit analysis is like the psychoanalysis of the electrical engineering world because itâ?Ts all about studying the behavior of circuits. With any circuit, you have an input signal, such as a battery source or an audio signal. What you want to figure out is the circuitâ?Ts output â?" how the circuit responds to a given input. More ...
Integrated Circuit Manufacturing Pattern Transfer
The integrated circuit manufacturing photolithographic pattern transfer process requires a variety of physical and chemical processes performed on a semiconductor substrate. More ...
Integrated Circuit Manufacturing BiCMOS Technology
BiCMOS is a technology that combines both CMOS and bipolar device structures in a single IC. The reason to combine these two different technologies is to create an IC chip that has the advantages of both CMOS and bipolar devices. More ...
Magnetism Permeability and Retentivity
Permeability is a property of a material that describes the ease with which magnetic flux is established in the material. Retentivity is a materials ability to retain a certain amount of residual magnetism after the magnetizing force is removed. More ...
Batteries
Early in the history of electrical science, laboratory physicists found that when metals came into contact with certain chemical solutions, voltages appeared between the pieces of metal. These were the first electrochemical cells. More ...
Integrated Circuits
An integrated circuit (IC) is a thin rectangular piece of semiconductor upon which, using a photographic process, thousands of electronic components, and the conducting paths to connect them, are printed. The types circuits that can be etched into a semiconductor chip range from amplifiers to logic gates and even microprocessors with millions of transistors. More ...
Magnetism
Magnetism is the force exerted by magnets when they attract metals or attract and repel each other. More ...
RC Filters
An RC filter can accept input sinewave signals and block certain bands of frquencies, thus allowing to pass only desired frquencies. This section describes passive RC filters. A passive RC filter uses only resistors and capacitors. More ...
CrowPi is a Raspberry Pi Project System Housed in a Laptop-Like Body
Learn everything about computers with this amazing Raspberry Pi kit housed in a laptop-like body. More ...
Zener Diode
A zener diode is similar to a standard diode allowing current flow in the forward direction except the semiconductor is more heavily doped and this allows it to operate in the reverse-bias break down mode. More ...
Electronics Lab
Even though an electronic circuit may appear to work on paper, and maybe even in a circuit simulator, it's always important to test it in the real world. Prototype circuits can be built using a solderless breadboard. More ...
How to Read a Capacitor's Values
Due to the limited space available for printing, physically small capacitors are especially difficult to read. Therefore capacitors use a wide variety of codes to describe their characteristics. More ...
Inductor Mutual Inductance and Coefficient of Coupling
Mutual Inductance the property of a coil in which it opposes the change of current in another coil. The coefficient of coupling between two coils is the fraction of magnetic flux produced by the current in one coil that links with the other coil. More ...
Integrated Circuit Manufacturing CMOS Technology
The MOSFET (metal-oxide-semiconductor field-effect transistor) is the dominant device used in modern integrated circuits because it can be scaled to smaller dimensions than other types of devices. More ...
