Expert Strategies: Tips & Tricks
Pro-Tip: The 'Virtual Ground' Rule
Always remember that Virtual Ground only exists if there is negative feedback and the open-loop gain is infinite. Never apply this logic to Comparators or Schmitt Triggers!
Logic: Op-Amp with Feedback
For almost all linear Op-Amp problems, the goal is to make the two input terminal voltages equal.
$$ V_+ = V_- \implies \text{Solve using Nodal Analysis} $$
