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 ...
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 ...
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 ...
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 Photoresist Process
The semiconductor photolithography process involves coating the substrate with A light-sensitive chemical layer called photoresist. Light is projected through a mask onto the substrate causings photoresists to react chemically. More ...
Magnetism
Magnetism is the force exerted by magnets when they attract metals or attract and repel each other. 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 ...
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 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 ...
RMS Used in AC Circuit Analysis
Because the value of an AC signal is continuously varying, it would be difficult to use formulas such as ohms law. In the specific case of a sine wave, the Root Mean Square (RMS) of the wave is used instead. More ...
Integrated Circuit Manufacturing CMOS Fabrication Sequence
Complementary Metal Oxide Semiconductor (CMOS) is used to fabricate digital circuits and IC chips. It is a combination of NMOS (N-type Metal Oxide Semiconductor) and PMOS (P-type Metal Oxide Semiconductor) transistor pairs. CMOS fabrication can be carried out in many ways. P-well is one of the processes in which CMOS fabrication is realized. More ...
The Diode
A diode is a semiconductor component designed to allow current to pass in one direction. To form a diode, a P type semiconductor is joined with an N type of the same semiconductor element, forming a P-N junction. Diodes are used for turning AC to DC, isolating signals, and mixing signals. 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 ...
Junction Field Effect Transistor (JFET)
A Junction Field Effect Transistor (JFET) consists of a channel and a pn junction. The gate controls the conductance of the channel. A JFET is a voltage controlled device, therefore no current flows into the gate. More ...
