Circuit element type Fixator.
A fixator is an ideal two-terminal circuit element which enforces both a fixed voltage and a fixed current between its terminals. It is thus neither a voltage nor a current source but rather both at the same time. Note that the netlist entry for fixators has a special form because two element values, a source current and a source voltage, must be specified. Fixators are hardly ever used for circuit analysis purposes. Their main application field is circuit sizing where they can be used to model operating points of nonlinear devices such as transistors.
