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 ...

1. This circuit uses a simple 50 Ω input termination to a non-inverting op amp. Circuit 2 employs transformer coupling with the signal applied to the non-inverting input of the op amp (Fig. 2). 2.
