OP-AMP tutorial
In this blog you can find opamp tutorial and circuits like differentiator integrator, summing amplifier and many more circuit. Operational amplifier basics detailed explanation and working of each circuit.
An operational amplifier is a DC-coupled high-gain electronic voltage amplifier amplifier that has high gain, differential input, high input resistance, and low output resistance.
There are mainly two types of opams amplifiers inverting amplifiers and others one is non inverting amplifier.
Difference Between Amplifier and Oscillator
In electronic systems, signals are often required to be either strengthened or generated. Two fundamental circuits that perform these roles are the amplifier and the oscillator. An amplifier is an electronic circuit designed to increase the amplitude of an input signal without significantly altering its shape. It takes a weak signal (such as from a […]

Schmitt Trigger Circuit Diagram, Working, Types and Applications
The Schmitt trigger is a bistable circuit widely used in digital and analog applications. It is primarily employed for signal conditioning, converting noisy, analog signals into clean, digital ones, and plays a critical role in eliminating the ambiguity associated with fluctuating or noisy input signals. A distinctive feature of the Schmitt trigger is the concept […]
3 Simple IR Proximity Sensor Circuits with Working & Applications
Here is a simple proximity sensor circuit which shows proximity of an object by LED bar graph. Also, you will see two other simple proximity sensor designs. Proximity sensors are devices that detect the presence of an object within a certain range without any physical contact. They are widely used in various applications such as […]
LM3915 Based LED VU Meter Circuit Diagram And Working
Creating an LED VU meter using the LM3915 involves designing a circuit that converts audio signals into visual LED bar displays. The LM3915 is an IC that drives 10 LEDs in a logarithmic scale, making it suitable for audio level meters. A VU meter, or Volume Unit meter, is an audio visualizer that uses a […]
