Description

The OpAmp is a simle nonideal model with a smooth out.v = f(vin) characteristic, where

OpAmp_equation1

The characteristic is limited by VMax.v (top) and VMin.v (bottom). Its slope at vin=0 is the parameter Slope, which must be positive (Therefore, the absolute value of Slope is taken into calculation.).

in_n (upper left) and in_p (lower left) are the input pins and out (right) is the output pin of the OpAmp.

Parameters

    OpAmp_0

  • Slope [-] : Slope of the out.v/vin characteristic at vin=0 (Slope): Scalar.
