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.

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.

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.

This model is a switched capacitor model without thermal behavior which can represent positive and negative resistances.
The clock source is inside the model, its frequency can be chosen by a parameter. Also the resistance is a parameter which can be positive and negative. The internal (switched) capacitor is parametrized in such a way that the total resistance is independently from the frequency equal to the resistance parameter.
