Gunn diodes are semiconductor devices which are used to generate low-power microwave signals in a simple and low-cost manner. These have been in use for more than 60 years now. Gunn diodes can work with frequencies ranging from a few gigahertz to over 100 GHz. It was first discovered by J. B. Gunn of IBM […]

Communication Protocols in Microcontrollers Explained
In this post I am going to explain various communication protocols that are used by microcontrollers, microprocessors and ICs for communicating with various sensors, electronic drivers, input and output devices. We will see: Why do communication protocols exist in electronics? UART protocol. I2C or IIC or “I squared C” protocol. SPI or Serial Peripheral Interface […]
Diodes: Working, How to Use, Applications
It’s John Ambrose Fleming (1849-1945), a British engineer, who invented the first diode in 1904, in the form of an electron tube. Later, with the development of semiconductor technology, the diode became a dipole consisting of two substrates: one, rich in free electrons, and of type N, the other deficient in electrons, and of type […]
SCR/Thyristor Circuit Configurations
Now in this article we will try to understand step by step how we can use this thyristor in practical work. That can be for controlling heavy loads like electric lamps, heaters, or motors and so on. So this part is more about real application and not only about theory. How We Trigger The Thyristor […]
Understanding Bipolar Junction Transistors (BJTs)
If we look at the diodes, their internal construction look very simple. They are made by joining two pieces of semiconductor material, and this is called a pn-junction. But when we talk about bipolar junction transistor or bjt, then things get little more complicated. It needs adding one more layer of semiconductor material, and that […]
How Load Conducts in Half-Bridge Driver Circuits like IR2184 or IR2110
Many folks, especially beginners, they get fully confused when they try to use a half-bridge driver circuits using ICs like IR2184 or IR2110. They look at the datasheet diagram and start thinking, “Bro, how the load will conduct? The MOSFETs are switching one by one so how the current will pass through the load? Looks […]
