Half Wave Rectifier Principle
Half Wave Rectifier : Half-Wave Rectifier Operation The below Figure illustrates the process called half-wave rectification. A diode is connected to an ac source and to a load resistor, RL, forming…
Basic DC Power Supply Circuit
All active electronic devices require a source of constant dc that can be supplied by a battery or a dc power supply. The dc power supply converts the standard AC voltage available…
Difference between ideal diode & conventional diode
An ideal diode is a diode that acts like a perfect conductor when voltage is applied forward biased and like a perfect insulator when voltage is applied reverse biased. So…
Ideal Diode Characteristics
The ideal model of a diode is the least accurate approximation and can be represented by a simple switch. When the diode is forward-biased, it ideally acts like a closed (on) switch,…
VI Characteristic of a Diode
As we know, forward bias produces current through a diode and reverse bias essentially prevents current, except for a negligible reverse current. Reverse bias prevents current as long as the reverse-bias…
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 and half is doped as an n region with a…
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 in a p-type material. Recall that p-type material has trivalent impurities…
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 a pentavalent impurity, a boundary called the pn junction is…
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 limited number of free electrons in the conduction band and holes…
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 that band. When an electron acquires enough additional energy, it…
