Re: "Smple" opamp circuits
Thanks for the link. It is interesting as a short introduction for people with no prior knowledge about rogowski coils and current probes.

"Smple" opamp circuits
Thanks for the post, Bill.

I agree with you, we need to be able to start working with simplified models and create flexible enough designs. This way we can incorporate new functionalities as we move to more complex models.

One example is the Rogowski Coil. It's model can be as simple as the one described in wikipedia:



But real world coils have construction imperfections and some other factors come into play.

Designing the integrator for the coil is also a non trivial task when looking for linearity, frequency response and stability.

Analog circuits inherently have some inaccuracies; if these exceed the allowable specification, there are three general strategies to dealing with them.

Analog, discrete-element filters have served us well for over a hundred years, but maybe we now need to focus education on filters for the GHz world, such as SAW and BAW devices?
