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 ...

Engineers often use SPICE simulations for operational amplifiers to look at the stability of a proposed circuit. SPICE simulations are particularly frequent for high-speed amplifier applications where ...

Download this article in .PDF format This file type includes high resolution graphics and schematics. Feedback systems have a wide range of applications including different types of amplifiers, signal ...

Fig 1. Shown is a basic TIA circuit used in dual-supply systems. Fig 2. Figure 1’s TIA circuit was modified for a single supply. Fig 3. Here, the TIA circuit in Figure 2 places a photodiode directly ...

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 ...

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 ...
