We took a look at op amp integrators in the previous article, Op amps do integration, so it makes sense to round out the picture by covering differentiator circuits. Of course, differentiation is the ...

Instrumentation amplifiers (INA) can sometimes throw you a curve ball for even the easiest applications. One would use an INA to gain a small differential signal to a usable voltage level in ...

We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and ...
