Op-Amp Stability Spice Model


In this document, Jan Petrik derives a Spice model for Op-Amp stability based on real-live bench measurements.

The document starts with the basics of operational amplifier stability and deals with the measurement of open-loop gain, open-loop output impedance, input impedance etc. The measurements are all explained in detail and common pitfalls are described.

Check out the application note below to learn more about stability of operational amplifier circuits and how to model them in Spice based on your own bench-measurements.
