In the Op-Amp shown in the figure, calculate the output voltage if the input voltage is: (a) 2V; (b) -2V. Use ideal diode assumption. (a) At vi = 2V: vi > 0, then vo < 0; D1 blocks and D2 conducts. (b ...

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 ...

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 ...

It is well known that combining a transformer with various types of amplifiers can improve the dynamic range. This works particularly well driving into the inverting side of either a differential dual ...
