Description

The Op-Amp block models an ideal operational amplifier (op-amp). The figure shows the implementation schematic.

The block implementation is based on the following assumptions:

These assumptions result in the following equations for the block:

equations
    v1 == p.v - n.v;
    v1 == 0;
    i1 == 0;
end

You can initialize the Current into output node variable prior to simulation. For more information, see Block-Level Variable Initialization.

Ports

The block has three electrical conserving ports.
