Op-Amps or Operational Amplifiers are called as the workhorse of Analog circuits. There are many types of Op-Amp IC, but the most commonly used ones are the LM358 and LM741. Based on the circuit design, Op-Amps can be configured for many applications like Amplifiers, Comparators, Integrators, Differentiators, Summer, Voltage Follower etc.. The below list from Circuit Digest consists of a huge collection of Op-amp Circuits with neat circuit diagram and practical DIY hardware explanation enabling you to master the operational amplifier basics.
Recently, we thought of building a simple FM receiver circuit, so, like always, we started googling for possible circuits that can be used to fulfil our requirements, and as expected, we found a lot of circuits on the internet, but the question remains, how good or useful will they be when we put those circuits to the test? Because just like us, we found a lot of…
Audio content has come a long way over the past decades, from a classic tube amp to modern-day media players, technological advancements have changed the way digital media is consumed. Among all these innovations, portable media players have become one of the first choices among consumers, because of their vibrant sound quality and long battery life. So how does it work, and…
Line follower Robot (LFR) is a machine that follows a line, it may be a black line or a white line. The line following bot is beginner-friendly and interesting to understand and build. While Line follower bots are popular and common to be built with Arduino or other microcontrollers, let’s try to build the same without a microcontroller and actually understand the logic…
One of the main applications for Schmitt triggers is interfacing signals between Analog electronics and Digital electronics, and translating levels within different logic families.
One major problem encountered during this process is the pickup of noise. Digital signals are inherently fast because they deal with high frequencies and fast-…
Operational Amplifiers or op-amps for short are perhaps the most widely used component amongst all analog electronics. Because of their versatility, only a few external components are needed to configure them to perform a wide range of tasks like amplification, addition, subtraction, multiplication, integration and so on, hence the name operational amplifier,…
The bistable multivibrator is one of those basic circuits which you might have learnt about in your high school or college, and you probably have built one with 555 timers or with discrete components like OP-amp, transistors, or resistors. These circuits are often viewed as simple educational circuits, but not so surprising they are also used in practical designs…
The multivibrator circuit is very popular and useful in the field of electronics, and it’s the most basic circuit that you will know about while learning basic electronics. The multivibrator circuit can be divided into two categories: the first one is known as the monostable multivibrator, and the second one is known as the astable multivibrator. But in this project, we will…
A zero-crossing detector circuit is a useful application of an op-amp as a comparator. This electronic circuit precisely identifies when an AC waveform transitions through zero voltage, tracking the changes in the sine waveform from positive to negative or vice versa while it crosses zero voltage. It can also be used as a square wave generator. They have many…
Almost all types of sensors and transducers convert real world parameters like light, temperature, weight etc into voltage values for our electronic systems to understand it. The variation in this voltage level will help us in analyzing/measuring the real world parameters, but in some applications like biomedical sensors this variation is very small (low-level signals) and…
An operational amplifier or Op-amp is one of the most commonly used components in any electronic design. It’s a very versatile device that can be used for a wide variety of applications. In our previous projects, we put the op-amps capabilities to the test by making a ton of projects with it, you can check those out if you want to explore more on the topic. We have also…
Most of the power supply these days are very reliable due to advancement in technology and better design preferences, but there is always a chance of failure due to a manufacturing defect or it can be the main switching transistor or the MOSFET going bad. Also, there is a possibility that it may fail due to overvoltage at the input, though protection devices like Metal Oxide…
In the modern world, we use batteries in almost every electronic gadget from your handheld mobile phone, digital thermometer, smartwatch to Electric Vehicles, aeroplanes, satellites, and even Robotic Rovers used on Mars whose battery lasted around 700 sols (Martian days). It is safe to say without the invention of these electrochemical storage devices a.k.a. Batteries, the…
