Circuit Analysis with Thevenin's theorem
Thevenins theorem states that Any linear electronic network containing only voltage sources, current sources and resistances can be replaced by an equivalent combination of a voltage source in a series connection with a resistance. 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 ...
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 ...
Operational Amplifier
An operational amplifier (op amp) is an amplifier circuit with a differential input, in other words it amplifies the voltage difference between its two inputs. The open-loop gain of an op amp is typically very large so normally, it's configured with negative feedback to reduce the gain. 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 ...
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 ...
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 ...
Integrated Circuit Manufacturing Bipolar Technology
Bipolar junction transistors (BJTs) are still used in integrated circuits (ICs) for switching, signal amplification, and radio-frequency circuits because they are faster than CMOS transistors. More ...
Introduction to Integrated Circuit Manufacturing
An integrated circuit is an ensemble of active (e.g., transistors) and passive devices (e.g., resistors, capacitors, and inductors) formed on and within a single-crystal semiconductor substrate and interconnected by a metallization pattern. 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
Magnetism is the force exerted by magnets when they attract metals or attract and repel each other. More ...
EMI, RFI, EMC, EMS, What's the Difference?
EMI, RFI, EMC, and EMS all refer to different aspects of radio frequency interference which may cause elecronic devices to malfunction. Correcting these problems can be an art and a science. More ...
Integrated Circuit Manufacturing E-Beam Lithography
Optical lithography high resolution, at low cost, but it has limitations. Electron-beam lithography uses an electron gun to generate a beam of electrons to produce submicrometer resist geometries without a mask. 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 ...
