All in one opamp testbench?

[iceburging]

Hi all.

Sometime ago I found a great schematic for characterising an opamp using a single testbench schematic (simulation only!). The problem is that I can now no longer find the image. Has anyone seen anything similar and know where I could find such a testbench described?

Thanks.

I believe you are referring to Ken Kundert's testbench A Test Bench for Differential Circuits.
