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 ...
What Is an Electronic Circuit?
Circuits provide a path for current to flow. To be a circuit, this path must start and end at the same point. In other words, a circuit must form a loop. More ...
Integrated Circuit Fabrication Photolithography
Photolithography is the process of transferring patterns on a mask to a thin layer ofphotoresist covering the surface of a semiconductor wafer. These patterns define the various regions in an integrated circuit, such as the implantation regions, the contact windows, and the bonding pad areas. More ...
Transforming Sources for Circuit Analysis
Kirchhoff's laws and Ohm's laws can get pretty laborious when you're analyzing complex circuits. Through a transformation technique, you modify a complex circuit so that in the transformed circuit, the devices are all connected in series or in parallel. After the transformation, you no longer need to systematically apply Kirchhoff's laws. More ...
Semiconductor Manufacturing Process Sequence
Semiconductor manufacturing consists of a series of sequential process steps in which layers of materials are deposited on substrates, doped with impurities, and patterned using photolithography to produce ICs. More ...
Electromagnetic Devices
Electromagnetic devices work based on the relationship between electrical current and a magnetic field. They are used to control valves, cooling and heating systems, relays, and electric motors. More ...
How to Calculate Impedance
Impedance is one of the most difficult things the electronics technician student needs to calculate. To calculate impedance, you must know the value of all resistors and the impedance of all inductors and capacitors in the circuit. Then you can calculate impedance using a simple mathematical formula. More ...
Integrated Circuit Manufacturing Packaging
Before ICs can be put to their intended use they must be packaged. The package is responsible for interconnecting, powering, cooling, and protecting the IC. More ...
Lithium Ion Battery Chemistry
Lithium-ion (Li-ion) batteries are one of the most common portable power sources used today. Impurities in the materials used to construct a lithium battery can cause it to overheat. More ...
Integrated Circuit Fabrication Masks
A mask in IC Fabrication is a master template for an IC design. A light-sensitive material, is applied on the wafer. The mask as well as a wafer are inserted in a lithography scanner. 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 ...
Integrated Circuit Manufacturing Deposition
Many different types of thin films are used to manufacture integrated circuits, including thermal oxides, dielectric layers, epitaxial layers, polycrystalline silicon, and metal films. This article addresses two techniques for depositing such films. 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 ...
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 ...
