Parameter for negative impedance converter
Extends from Modelica.Icons.Record (Icon for records).
Information
This record calculates the analytic parameters from source voltage and resistances of the implementation with opAmps. Looking at the formula, it is easy to design the opAmp circuit from desired analytic parameters:
R = 1/gPos
Rg= -1/gNeg
Vs= VLim*(Rg + R)/Rg
