Voltage Controlled Current Source

Netlist Entry

Gxxxx nout+ nout- vc+ vc- transconductance
nout+ Positive output node
nout- Negative output node
vc+ Positive control node
vc- Negative control node
transconductance Output current/Input voltage (Siemens or mhos)

SPICE2 polynomial sources are also supported in order to maintain compatibility with commercially available libraries for IC's. (Most operational amplifier models for example use several polynomial sources). In general, however the arbitrary source is more flexible and easier to use.

The netlist format for a polynomial source is:

Gxxxx nout+ nout- POLY( num_inputs ) vc1+ vc1- vc2+ vc2- ...
+ polynomial_specification
vc1+ etc. Controlling nodes
num_inputs Number of controlling node pairs for source.
polynomial_specification See Polynomial Specification.
