Miniscule discrete op-amp

[ThorstenL]

Konnichiwa,

The idea is to create a discrete op-amp small enough to directly replace a DIP8 IC op-amp, ideally surpassing the performance of one of similar cost

You might want to try to build up something based around diamon transistor structures. In that case you have an exceptional I/V converter or buffer. J-Fet frontends can be used as well as adding a J-Fet buffer to the negative input to achieve high input impedances on both inputs for other circuits.

Inspired by Mr Evil's work, this is my own attempt :

Hi

These and the PNP comp are great for low power CCS and mirror circuits, if space is a real concern. These are good space savers as well.
