Techniques for Compensating Inductor SRF

Can anyone recommend a technique for compensating for inductor self-resonant frequency (SRF) in power inductors used in damped low pass filters? Example circuit below: How should I compensate for the self-resonant frequency of inductor Z1? Let's…

What happens to parasitic capacitance and inductance in a superconductor?

Do the parasitics also become [more] ideal? Or are all changes solely due to the perfect conduction? If not, how are the parasitics affected? Such basic information seems necessary to engineer any purpose-built device utilizing superconductors,…

Non-ideal Non-inverting op amp

This is probably more of an algebra question. I do not understand where the "1"s come from in equation 1.10 given the much simpler voltage divider equation in the line just above it. And why do they convert a simple resistor division problem, into…

Modeling input bias current in op amp

I was trying to understand the non-ideality of op-amps, and specifically how the input bias current is modeled. The image was taken from a nice Youtube tutorial (Mateo Aboy - DC Offsets). The input bias current (\$ I_{b+} \$ and \$ I_{b-} \$) are…
