Forward Bias & Reverse Bias of a Diode
A diode is made from a small piece of semiconductor material, usually silicon, in which half is doped as a p region ... -
Energy Diagrams of PN Junction & Depletion Region
The valence and conduction bands in an n-type material are at slightly lower energy levels than the valence and conduction bands ... -
How a PN Junction Formed in a Diode
When you take a block of silicon and dope part of it with a trivalent impurity and the other part with ... -
N Type and P Type Semiconductors
Semiconductive materials do not conduct current well and are of limited value in their intrinsic state. This is because of the ... -
Band Gap for Semiconductor Materials
The valence shell of an atom represents a band of energy levels and that the valence electrons are confined to ... -
Insulators, Conductors and Semiconductors
All materials are made up of atoms. These atoms contribute to the electrical properties of a material, including its ability to ... -
Dependent Current Source
A dependent current source establishes a current, which is independent of the voltage across it, that is determined by the ... -
Current Divider Rule
It can be quite useful to determine how a current entering two parallel resistors “divides” between them. Consider the circuit shown ... -
Voltage Divider Rule
It can be quite useful to determine how a voltage appearing across two series resistors “divides” between them. Consider the ... -
Combining Independent Current Sources in Parallel
It is not possible to combine independent current sources in series, since this would violate KCL. However, consider the parallel ...
