{{Note|If you want to use a B-type nonlinear dependent source in the Netlist definition of an active one-port or two-port, it must be contained in a subcircuit definition rather than in the main circuit.}}
The figure below shows the geometry of a two-port amplifier device with microstrip input and output transmission lines. The Netlist of the two-port device uses is given below: ---- C1 1 0 1p R1 1 2 50 E1 2 0 1 0 20 RS 2 3 10 R2 3 0 50 C2 3 0 1 ---- In this case, the input and output nodes are 1 and 3, respectively. The same Netlist can be written using a B-type nonlinear dependent source as follows:
