PWM stands for pulse width modulation which signifies the variable nature of the pulse widths that may be generated from a particular source such as a discrete IC, MCU, or a transistorized circuit. What’s PWM In simple terms a PWM process is nothing but switching ON and OFF a supply voltage at a particular rate […]

How to Use Resistors with LED, Zener and Transistor
In this post I have explained how to use resistors while designing an electronic circuits using LEDs, zener diodes, or transistors. This article can be very useful for the new hobbyists who normally get confused with the resistor values to be used for a specific component and for the desired application. What is a Resistor […]
Notch Filter Circuits with Design Details
In this article I will provide a detailed explanation regarding how to design notch filters with precise center frequency and for maximum impact. Where Notch Filter are Used Notch filter circuits are normally used for suppressing, nullifying, or cancelling a particular range of frequencies in order to avoid an annoying or unwanted interference within a […]
How to Compare IGBTs with MOSFETs
In this post I have explained the main differences between an IGBT and a MOSFeT device. I have explained more about the facts from the following article. Comparing IGTB with power MOSFETs The insulated-gate bipolar transistor features a voltage drop which is significantly low when compared to a conventional MOSFET in the devices which have […]
How to Protect MOSFETs – Basics Explained
In this post I will comprehensively explain how to protect mosfets and prevent mosfet burning in electronic circuits by following some basic guidelines related to correct PCB layout, and careful manual handling of these sensitive devices. Introduction Even after connecting everything correctly you find the mosfets in your circuit becoming HOT and blowing off within […]
Digital Buffer – Working, Definition, Truth Table, Double Inversion, Fan-out
A buffer stage basically a reinforced intermediate stage which allows the input current to reach the output without getting affected by the output loading. In this post I will try to explain what digital buffers are, and we will be taking a look at its definition, symbol, truth table, double inversion using logic “NOT” gate, […]
