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.
Here is the circuit diagram of a peak detector circuit using opamp. A peak detector circuit is used to determine the maximum (peak) value of an input signal. It stores the maximum value of the input signal for a very long interval of time. In many applications we need to measure the maximum value of […]
The precision rectifier is a type of rectifier that converts the AC signal to DC without any loss of signal voltage. In a precision rectifier circuit using opamp, the voltage drop across the diode is compensated by the opamp. In a Diode voltage drop is around 0.6V or 0.7V. Also, this circuit can be made […]
A Schmitt Trigger circuit is a comparator circuit with some modifications. As compared to a normal comparator circuit the Schmitt trigger circuit has a hysteresis curve. This means that it has two threshold voltages an upper threshold and a lower threshold voltage. In Schmitt trigger hysteresis is created by applying positive feedback to the non-inverting input […]
Voltage controlled oscillator circuit is an electronic oscillator circuit whose output frequency is controlled by an input voltage source. By varying the input voltage, we can change the output frequency. A voltage controlled oscillator can produce frequencies ranging from few Hertz to tens of Gigahertz. Voltage to frequency converters is used in frequency modulation FM […]
In this article, we will discuss how we can make a triangle wave generator using opamp. So, let’s start discussing how to make a triangle wave generator. A triangle wave is consisting of a constantly rising and falling slope. An opamp integrator gives a triangle wave. If you are an electronics student then you might […]
Have you thought about who turns on and off those street lights on the road? Turning on and off those street lights may be a boring task. We can make this process automatic by a simple automatic street light circuit. Also, you can automate your home lighting, lights in the garden, and other outside places […]
