I'm currently taking a circuits class that discusses various transistor amplifier configurations eventually culminating in building an op-amp. This includes various configurations such as the darlington pair, cascades, or cascode transistors. Are there any good online resources I could check out to help me study that you guys know of? I've been looking for awhile now but all my searches overwhelmingly return results for basic circuits 1 classes, and I can't seem to find what I'm looking for.
Thanks in advanced.
