Definition of an IC-CAP Circuit

IC-CAP defines a circuit as any connection of two or more components. Previous chapters have dealt primarily with single devices such as bipolar, GaAs or MOS transistors. An IC-CAP circuit can be a simple two-resistor voltage divider or a complex operational amplifier or A/D converter.

The circuit, like a single device, is specified in the Circuit folder of the model window using SPICE compatible circuit definition syntax. All circuit decks in IC-CAP begin with the .SUBCKT subcircuit definition and end with the .ENDS statement. Circuit modeling allows more accurate solutions to many single device modeling requirements and expands the level of systems modeling possible.
