The goal here is to have a page of various transistor circuits, but for now I'll include op amps.

They should be simple enough that you could combine them in a larger design (i.e. as part of an op amp or ASIC). I'm not going to include fundamental circuits (such as: https://en.wikipedia.org/wiki/Template:Transistor_amplifiers or basic op amps which you can find in Electronics for Inventors or AoE.)

These are sometimes called Topologies. Like a map. A map topology. If maps lie, then it's likely these circuits will lie as well. Expect any examples to be missing required components to work.
