Depletion Region Formation: In a P- region holes are majority charge carriers and electrons are minority charge carriers. Also P- region have accepter ions. In N- region, electrons are majority charge carriers and holes are minority charge carriers. Also N- region have donor ions. From the P – region holes spread into the N- region. […]
Biasing of PN Junction Diode: Depletion region is created when PN junction is formed. Due to this depletion region, movement of electrons and holes stops. So the current flow through the PN- Junction is zero. If we want to make the current to flow through the circuit we have to bias the PN junction diode.
Intrinsic Semiconductor A semiconductor is called intrinsic when it’s impurities content is less than one part impurity in 100 million parts. Most commonly used semiconductor are silicon and germanium. In figure there are four electron in the outermost orbit. Each of the four valance electron takes part in forming covalent bond with the four nearer
Difference between Intrinsic and Extrinsic Semiconductor Read More »
Intrinsic semiconductor have small conductivity at room temperature. So we didn’t use intrinsic semiconductor. By adding some amount of impurity atom to a intrinsic semiconductor we can change the conductivity of intrinsic semiconductor. The process of adding impurity atom to intrinsic semiconductor is known as doping. In doping one atom of impurity is added per
A semiconductor which is in pure form is known as intrinsic semiconductor. A semiconductor is called intrinsic when it’s impurities content is less than one part impurity in 100 million parts. Most commonly used semiconductor are silicon and germanium. In figure there are four electron in the outermost orbit. Each of the four valance electron
An operational amplifier is an electronic component which is used in analog circuit to amplify signals. It have two input terminals one is inverting and another one is non inverting terminal, and one output terminal. Op-amp are used in various applications such as signal conditioning, filtering, amplification, integration, differentiation and many more. Block Diagram Input

In this article firstly we will study the ideal characteristics of operational amplifier then we will discuss the characteristics of practical operational amplifier . Ideal Characteristics of Operational Amplifier Ideal operational amplifier has two input signal V1 and V2 which is applied to non inverting and inverting terminal. The input currents I1 and I2 are
1. Common Base Configuration In common base configuration, the base of the transistor is made common. The input is applied between the base and the emitter terminal. The output is taken between collector and base. 1.1) Current Gain of Transistor in Common Base Configuration: In this configuration emitter current is the input current and collector

What is BJT? A BJT, or Bipolar Junction Transistor, is a tiny electronic component that can amplify or control the flow of electric current in a circuit. It’s like a switch that uses a small current to control a larger current. BJT Construction A transistor is a single crystal of silicon (Si) or Germanium (Ge).
What is Tunnel Diode? It is a special type of semiconductor device that behaves quite differently from regular diodes. What sets it apart is its ability to display negative differential resistance within a specific range of voltages. This means that as the voltage applied to the diode increases, the current passing through it actually decreases,
