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 ...

Christophe P. Basso has written a new book: Linear Circuit Transfer Functions—An Introduction to Fast Analytical Techniques.

The transfer function—gain and phase as a function of frequency—provides valuable information about a control loop’s speed and stability. Knowing a control loop’s transfer function, as well as the ...
