3.9  Voltage Controlled Admittance

3.9.1  Syntax

Preferred syntax:
.VCG label n+ n– nc+ nc– expression
Alternate syntax:
Gxxxxxxx n+ n– VCG nc+ nc– expression

3.9.2  Purpose

Voltage controlled admittance.

3.9.3  Comments

N+ and n– are the positive and negative element (output) nodes, respectively. Nc+ and nc– are the positive and negative controlling nodes, respectively. Value is the transfactor in mhos per volt.

The simulator will faithfully give you a negative admittance if it seems appropriate. Usually, this part is used with a behavioral modeling function, like PWL, which allows you to specify a table of admittance vs. voltage.
