Controlled Sources

H Source

The "H" Source is a linear Current Controlled Voltage Source.

1 Place or attach a symbol to a model of specification, such as:

.MODEL CCVS_xn H(g=1 )

2 In the dialog setup of the symbol, set the parameter field to the reference designator name of a voltage source on the schematic that is to control the source.

F Source

The "H" Source is a linear Current Current Voltage Source.

1 Place or attach a symbol to a model of specification, such as:

.MODEL CCCS_xn F(g=1 )

2 In the dialog setup of the symbol, set the parameter field to the reference designator name of a voltage source on the schematic that is to control the source.

B Source

The "B" source allows an output current or voltage to be generated from a behavioral expressions of voltage and currents of node voltages or currents through voltage sources.

1 Place or attach a symbol to a model of specification, such as:

.MODEL bsource_i_xn B(b=1 )

.MODEL bsource_v_xn B(b=1 )

Note the b=1 is a dummy, and not used.

2 In the parameter field of dialog setup of the symbol, set the parameter field to the required expression of voltage and currents, e.g.

i=-1e-03*tanh(v(vin))

v=v(vin)*v(vin)
