After my last Signal Chain Basics article, The basics of op amp loop-stability analysis: A tale of twin loop-gains, I received questions about how to generate the open-loop SPICE simulation curves ...

Let’s say that for a project you are working on, you need an op amp (of course, I would like it to be one of one of Touchstone’s op amps), and you want to make sure that the amplifier meets your ...

Part 2 shows the impact of adding the tee to the op-amp loop gain plot. Mapping that back to the design algebra then reveals the impact the tee has on output noise. The tee network algebra of Part 1 ...
