CD4008 4-Bit Full Adder IC : Pin Configuration, Working & Its Applications

By

In digital electronic devices, like computers/processors, adders are the digital logic circuits designed for ALU operations such as the addition of 2 or more binary numbers, address calculation, address calculation, increment and decrement operations, counting, table indexes, etc. Because the bits flow and computation in these logic circuits ensure the performance, functionality, and performance of the computers. This article describes the 4-bit full adder that is available in CD4008 IC and used … [Read more...]

MX1508 DC Motor Driver : Pin Configuration & Its Applications

By

When a conventional geared DC motor is connected directly to the output of the ICs such as Atmega16, microcontrollers, 555 timers, and 74 series ICs the motor might get damaged. Because these ICs cannot provide at least 250mA of current required for the DC motor. Therefore, to drive the DC motor, a circuit (with transistors or relays or L293D/L298) is needed that can work as a bridge between the motor and the IC. Hence, the manufacturers and hobbyists use several IC motor driver modules in … [Read more...]

What is Schottky Diode : Working & Its Applications

By

The Schottky diode, also known as a hot-carrier diode or leaky-carrier diode, is the most popular semiconductor diode invented by Walter H. Schottky in 1926. In the early days, wireless devices & metal rectifiers used cat’s whisker detectors within power applications and these detectors can be considered as primitive Schottky diodes. So, let us see why a Schottky diode is so special? What is Schottky Diode? A Schottky diode is a special type of metal-semiconductor junction diode that … [Read more...]

What is a Freewheeling Diode : Circuit & Its Working

By

In different circuits, a switching element switches at a fixed frequency to manage the load’s voltage. Once the switching element activates then an extremely high voltage spike because of the stored energy within the magnetic field of the inductive load comes into view across the switching element terminals in switch OFF condition so, it may destroy the switching element. To disperse this energy, the freewheeling diode is utilized. When the switching element is deactivated then the load can … [Read more...]

What is a Crystal Diode : Construction & Its Working

By

A diode is a semiconductor device through which current supplies in one direction only. The initial diodes were crystal diodes which are used as rectifiers in radio kits. In this diode, a weak signal was fed into the crystal material using a very fine wire namely the cat's whisker. The crystal material in the diode removes the high-frequency carrier signal of radio by allowing the elements of the signal through the audio data to approach through clear. The crystal material was packed with … [Read more...]

What is IMPATT Diode : Construction & Its Working

By

The concept of IMPATT diode was actually invented in the year 1954 by William Shockley. So, he expanded the idea for producing a negative resistance with the help of a mechanism like transit time delay. He proposed the injection technique for charge carriers within a PN junction is forward biased and published his thought in the Technical Journal of Bell Systems in 1954 and titled with the name 'Negative Resistance Occurring from Transit Time within Semiconductor Diodes. Further, the proposal … [Read more...]
