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 ...

An op-amp operates on analog input. It can be used to amplify or attenuate this input, and to carry out mathematical operations such as addition, subtraction, integration, and differentiation. Because ...

I built and compared two non-inverting amplifier circuits in LTSpice: one using an ideal op-amp model and the other using a real LT1006 op-amp. The goal was to see how closely a real op-amp tracks the ...

Did you ever wonder how to calculate the stability of an op amp circuit? Put the wrong compensation network into the feedback loop, and you’re got an attenuator or, worse, an oscillator. It’s not ...

The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

Op-amp in open-loop configuration has a very few application because of its enormous open-loop gain. Controlled gain can be can be achieved by taking a part of output signal to the input with the help ...

In the measurement industry, a very crucial functional block is a Programmable Gain Amplifier (PGA). If you are an electronic enthusiast or a college student, you have probably seen a multimeter or ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

Members can download this article in PDF format. In designing an input stage for an analog-to-digital converter (ADC), engineers choose a particular amplifier, assign a target gain, and note the ...

The inverting op-amp configuration is a crucial part of analog circuit design, widely used for signal amplification with a phase inversion. One of the key design decisions in this configuration ...
