Experts in electronics engineering often say, "Analog circuit design is like black magic." What is that supposed to mean
Analog circuit design is more of a craft than a science.
You can be taught the theory, but you have to serve an apprenticeship of doing to become competent.
That's true of a lot of things but particularly so for analog, where so many unexpected parameters play a part.
One of the great wizards of analog was the late Bob Pease, the legendary analog circuit designer at National Semiconductors.
Bob wrote hundreds of columns and application notes, and his archives are one of the greatest analog resources on the web.
