Utility components used by package Examples
This package contains some utility components used by package examples. These components are auxiliary components that should not be used like true MLS components since they are designed the purpose of the examples only, not for common use.

Modelica.Electrical.Analog.Examples.Utilities.NonlinearResistorChua's resistor
This is the only nonlinear component for Chua';s circuit. It is a piecewise linear resistor with both an inner and an outer range, which includes the inner one. The slopes of both ranges are given by parameters. The resistance characteristic is continuous. For Chua';s circuit both slopes have to be chosen to be negative.

Modelica.Electrical.Analog.Examples.Utilities.TransistorTransistor with resistance an capacitance
Since the simple bipolar transistor model does not have base or collector resistances both are added in this component. Additionally, a capacity is added to the base pin. See the schematic for more details. In such a way the transistor model can be enhanced to become more common.
