@sheepdoll--To your point"Regarding the demise of analog engineering. It seems that analog circuits like the example posted are easy to solve with field equations in a simulator (Ironically digitally implemented.) Are we too dependent on such tools such as Matlab, and pSpice which can add to the cost of the project?"
Expertise in analog layout and design is still the key to a good analog designer. My analogy of a doctor: you go to medical school and learn it all and then you specialize----engineers need to do that better than we do now and continue to learn always
