Gxxxxxxx n+ n- nc+ nc- value
Gxxxxxxx n+ n- nc+ nc- expression
.VCCS label n+ n- nc+ nc- expression
Voltage controlled current source, or transconductance block.
N+ and n- are the positive and negative element (output) nodes,
respectively. Current flow is from the positive node, through the source,
to the negative node. Nc+ and nc- are the positive and negative
controlling nodes, respectively. Value is the transconductance in
mhos.
