These common op-amp circuits are useful for amplifying various analog signals. The ideal op amp model helps us understand how these circuits operate. For more detailed information on op amp circuits, ...

Op amps are pretty dang cool, with a lot of neat circuits you could build using them. I actually just put the finishing touches on my first actual op amp design and sent the design files over to ...

It is by no means a good op-amp by the standards on any era but 1964, as does not have a very high gain, has no short-circuit protection, and requires an external capacitor for frequency compensation.

4. An improved multiple-input op-amp summer can be analyzed more easily than the one in Figure 3. This is because the general design equation can be expressed more simply (Equation 4).

In the last column (Simulating op amp noise) I showed how to do simple and fast simulations on op amp circuits to get a handle on what kind of noise performance to expect.As can be expected with any ...

An op amp is usually configured with external input and feedback resistors to set the gain and other characteristics of the circuit. A comparator usually runs open loop; i.e., no feedback.
