Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

An instrumentation amplifier (INA) built using three operational amplifiers (op amps) can provide performance advantages in terms of high input impedance, low output impedance, easily adjustable gain, ...

The Lock-in amplifier tutorial [1] will help students understand basic and some advanced concepts related to the principle of operation and use of a lock-in amplifier (LIA). It is intended for use by ...

An operational amplifier or op-amp is simply a linear Integrated Circuit (IC) having multiple-terminals. The op-amp can be considered to be a voltage amplifying device that is designed to be used with ...

Even though the operational amplifier, or op-amp, is not a discrete component like a resistor or a capacitor, its behavior is described by a few simple rules that are as easy to understand as those of ...

Abstract: Frequency compensation of two-stage integrated-circuit operational amplifiers is normally accomplished with a capacitor around the second stage. This compensation capacitance creates the ...

Circuit simulations are great because you can experiment with circuits and make changes with almost no effort. In Circuit VR, we look at circuits using a simulator to do experiments without having to ...

The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

Op amps are the basic building blocks for much of linear circuit design. You probably learned about them in college and even designed some products containing an op amp. As an electronic engineer, you ...
