Today, these devices are fabricated as small integrated circuits, but the concept started long ago using ... that if the op amp gain is really big, then enough feedback will be applied to the ...

For instance, op-amp input capacitance has a nonlinear behavior that’s a function ... circuit will exhibit large input impedance on dc as well. Figure 3 shows how the circuit can be adapted to ...

Combing multiple channels of audio is a perfect use for this circuit. The traditional inverting op-amp summer configuration ... The transfer function in Equation 9 shows the voltages to sum ...

When implemented well, using an appropriate op amp ... the exact opposite of the circuit's intended function. To improve stability, start by measuring the op amp's impedance. Measuring the stability ...

A lifetime of amassing random pieces of test equipment has left me with a gap in my armoury, namely that I don’t possess a low frequency function generator ... NE5532 dual op-amp that presumably ...
