Introduction to Gas Sensors: Construction Types and Working

A Typical human nose has 400 types of scent receptors enabling us to smell about 1 trillion different odours. But still many of us do not have the capacity to identify the type or…

Introduction to Schmitt Trigger

What is a Schmitt Trigger? A Schmitt trigger is a comparator (not exclusively) circuit that makes use of positive feedback (small changes in the input lead to large changes in…

Buck Converter: Basics, Working, Design and Operation

Many a times in the electronics world we find the need to reduce one DC voltage to a lower one. For example we may need to power a 3.3V microcontroller from a 12V supply rail. The…

Introduction to Digital to Analog Converters (DAC)

When talking about signals, they can be broadly classified into analog signals and digital signals. All Digital Electronics like Logic Gates, Flip-Flops, Microcontroller,…

Introduction to Analog to Digital Converters (ADC Converters)

We live in an analog world, surrounded by digital devices. Everything we see, feel or measure is analog in nature such as light, temperature, speed, pressure etc. But most of the…

What is Voltage Regulator and How Does It Work?

Most of the Integrated IC’s require a constant voltage with which it could operate. Be it a simple Logic Gate or a complex microprocessor they have their own operating voltage.…

What is Optocoupler and How it works?

If you’ve ever taken apart any phone charger or a switching power supply, you’ll find some tiny black IC packages with an unusual number of pins, mostly four or six, both in SMD…

Boost Converter: Basics, Working, Design & Operation

We’ve all come across pesky situations where we need a slightly higher voltage than our power supplies can provide. We need 12 volts, but have only a 9 volt battery. Or maybe we…

Introduction to Diodes: Basics, Types, Characteristics, Applications & Packages

While the Resistors, Capacitors and Inductors form the basic elements of a circuit, it is the semi-conductor device that actually holds the magic within. Every electronic circuit…
