January 13, 2011 -- Part 1 of this article looked at what makes an amplifier unstable, and worked through a high-speed low-noise transimpedance amplifier (TIA) stability example. Armed with a good PSpice-based analytical method to investigate proper compensation and having found the value which simulates to give the best response, the next step is to verify the simulation results on the bench.
