Description

The Ideal Op Amp component models an ideal op-amp by enforcing a virtual short between the positive and negative inputs.

The component is a two-port. The input port is a nullator, that is, fixes the voltage and current to zero. The output port is a norator, that is, supports any voltage or current.
