Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with ...

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 ...

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 … ...

The operational amplifier (op-amp) is a high performance gain device with essentially linear qualities.

Minimizing the noise effects of electric and magnetic fields on op-amp circuits does not require a magician. A step-by-step procedure can tame such interference. Once you understand the basis of noise ...

Fig. 2: Unity-Gain Follower (Non-Inverting) With the invention of the transistor in 1947 (see our related Milestone article “The Transistor Portable Radio”), a parallel development program of tube and ...

New operational amplifiers optimized for high-performance audio and ultrasound applications combine extremely low total harmonic distortion plus noise (THD+N), -130 dB, with large ...

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 ...
