Op-Amp Stability Basics - Part 2
This video will focus on op amp output impedance, as a critical parameter for op amp stability, especially when driving capacitive loads.
The output Impedance definitions of Zo and Zout will be derived. How to predict op amp stability by plotting op amp Zout and load impedance Zload will be taught. Often an application is bounded by the op amp used, its main feedback components and the application load. The only stability knob to turn will be 1/Beta. Modification of the input network and feedback network will be presented.
