MNA with Capacitors, Inductors and Op-Amps

MNA with Op Amps. Applying modified nodal analysis to circuits with ideal operational amplifiers (op- amps) is a bit more difficult. Each op-amp increases the count of voltage sources by 1 (because the output of an op amp is treated as a voltage source), but also complicates the creation of the MNA matrices.

Why are capacitors treated as shorts in small signal models?

When you''re analyzing a circuit to find the DC operating point (sometimes called the Q-point), you indeed treat capacitors as open circuits. Small-Signal Analysis and AC: Once the DC bias point is determined, small-signal analysis looks at how the circuit behaves for small deviations around this point due to small AC signals. Even …
