Non-linear capacitance computation of Ebers-Moll BJT
Extends from Modelica.Blocks.Interfaces.SISO (Single Input Single Output continuous control block).
Information
This block computes the junction capacitance value of a junction capacitance in accordance with the Ebers-Moll junction diode model. No temperature variation is considered in this model.
