Circuit Building Blocks

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)
