Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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.
