In the digital electronic circuits, one of the basic essential devices is diodes. A diode consists of two terminals. These two terminals connected to the supply results in conduction. The way the terminal sare connected makes it classified as a forward-biased diode or reverse-biased diode. In forward bias, the diode allows the current to flow through it. During reverse bias, it blocks the flow of current. This reverse biasing is used in the case of the varactor diode. Based on the c … [Read more...]
Zener Breakdown and Avalanche Breakdown
A diode is an electronic component that consists of two electrodes. These two electrodes are the positive electrode and the negative electrode. These diodes are composed of semiconductor materials like germanium, silicon, and selenium. The most important property of diodes is that they are capable of conducting current in one direction only. Diodes are used as voltage regulators, switches, rectifiers, etc. A PN junction diode is a type of diode that has a negative side (n) and a positive side … [Read more...]
What is Diode Approximations : Types & Its Problem
Diode Approximations are how the Diodes present in the circuit gets analyzed. The diode can be considered as the basic electronic device in any type of circuit. These are of various types a design criterion is based on the requirement. The analysis of it can be done based on the Three approximations. Each approximation can be done by considering the diode as a switching element. For these basic components called Diodes, there exist three approximations. In each one, the initial and the … [Read more...]
Zener Diode Working and Its Characteristics
A basic semiconductor diode can operate in forward bias but it cannot conduct during reverse bias. The special type of diode that can conduct in reverse bias is referred to as a Zener diode. This diode can conduct in forward bias just like a normal diode. The junction for the Zener diode will be heavily doped. Because of this reason, it can work as normally as a basic junction in forwarding bias and can tolerate the reverse currents during reverse bias. The main purpose of it is to use in … [Read more...]
Types of Diodes and their Applications
A basic diode consists of two terminals. This terminal is referred to as anode and cathode. It has a property of conducting the flow of current in a single and unified direction. This basic property of the diode makes it as a basic building block in the power supply units. because there it is preferred in the process of rectification. It is used during the modulation of the signals. There exist many uses for the diodes based on the requirements in various fields of electronics as well as … [Read more...]
Zener Diode as Voltage Regulator
A Zener diode is a type of semiconductor diode. Generally, a normal diode with p and n junction will not function or blocks the flow of the charge carriers’ results in no flow of the current is seen during the reverse biasing of the device. Hence this condition is known as Breakdown. The main purpose of designing this device is to make the device to conduct in the reverse biasing condition. It can normally function just like a diode with p-n junction in forwarding biased condition. In this type o … [Read more...]
What is Zener Breakdown & Avalanche breakdown & their differences?
In a basic semiconductor, a junction is formed due to the interaction between p-type and n-type. This junction can be dope heavily or lightly based on circumstances. As it is already known that a basic diode that is of junction p-n can conduct during forward bias. Once the stage of reverse bias entered it cannot conduct and some breakdowns arise. These are mainly due to the multiplication of the carriers as well as due to the doping concentration made high at the junction. There are two types … [Read more...]
