Op-Amp

Ideal operational amplifier

Library

Electrical Elements

Description

The Op-Amp block models an ideal operational amplifier (op-amp). If the voltage at the positive pin is denoted by Vp, and the voltage at the negative pin by Vm, then an ideal op-amp behavior is defined by Vp = Vm. In other words, the op-amp gain is assumed to be infinite. By implication, the current from the Vp to the Vm terminal is zero.

Dialog Box and Parameters

The Op-Amp block has no parameters.

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

Ports

The block has three electrical conserving ports.
