EXTENDED ADMITTANCE DESCRIPTION OF NONLINEAR N-POLES

The extended admittance description that shall be introduced is a desc ription in which pin currents are a function of pin voltages and addit ional signals. The extended admittance description exists for every Li near and nonlinar analogue network element. That means, a general meth od for analog macromodelling is given by this description. An experime ntal implementation of a model interface uses the extended admittance description. It demonstrates that networks with usual and even unusual elements can be both described and simulated. The proposed descriptio n touches questions concerning the standardization of analogue extensi ons of VHDL.
