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 ...
The key op amp specifications for a voltage feedback op amp in this application are the gain bandwidth product (GBP) and the phase margin (PM). Figure 1 shows the open-loop gain and phase vs.
