Steps to check a diode with a multimeter, follow these steps: If you do not have a multimeter with a diode testing mode, you can perform a simple resistance test to check the diode. Here are the steps: Note: This resistance test will not give you the voltage drop across the diode, but it can … Read more
To understand how to characterize a voltage controlled current source (VCCS)? We must know about VCCS. Voltage-controlled current source (VCCS) is an electronic device that produces a current that is proportional to an input voltage signal. To characterize a VCCS, you need to determine its transfer function, which relates the output current to the input … Read more
Modern electronics have a PN junction diode as an important component. It is made by joining P and N type semiconductor materials. There are many ways to form a PN Junction Diode. Each method has its advantages and disadvantages. There are three main methods to explain the formation of pn junction diode: the diffusion, epitaxy, and ion-implantation. … Read more
The term “bias” in electronics refers to the direction of the voltage applied to a device, such as a diode. There are two types diode biases: forward bias or reverse bias. Both types of bias can have different effects on diodes and their operation. It is important to understand the difference between reverse bias and forward bias … Read more
A PN junction diode is a type of semiconductor device that allows current to flow in only one direction, from the p-type material to the n-type material. The flow of current in a PN junction diode depends on the voltage applied across it, which determines the bias of the diode. In this article we will … Read more
The variation of diode current with the applied voltage to the junction diode is known as the characteristics of PN junction diode. Basically there are 2 types of characteristics of pn junction diode i.e. Forward bias characteristics and Reverse bias characteristics. Characteristics of pn junction diode Forward bias characteristics. Reverse bias characteristics. Forward bias characteristics of … Read more
In this article we will discuss about How to obtained xor gate using nand gate, Truth table for XOR gate, Applications of XOR gate in digital electronics. XOR gate is a fundamental building block in digital electronics that outputs a high (1) signal when the number of high (1) inputs is odd, and a low … Read more

Current gain in Common Base Transistor Large signal current gain (α) D.C. current gain (αdc) Small signal current gain (α‘or hfb). Large signal current gain (α) … Read more
Semiconductor are classified into two classes: Intrinsic (or pure) semiconductors Extrinsic (or impure) semiconductors Intrinsic Semiconductors A semiconductor in an extremely pure form is known as intrinsic semiconductor. A semiconductor is not truely intrinsic (or pure) unless its impurity content is less than one part in 100 million parts of semiconductor. In an intrinsic semiconductor, … Read more
Static and Dynamic resistance of Diode In a junction diode, applied voltage (V) is not proportional to the diode current and hence it does obey Ohm’s law. So junction diode is the example of non-ohmic conductor. The resistance of a is the function of the operating current. Diode has two possible resistances i.e. d.c. or … Read more
