Simulators

This model is supported only by the HPSPICE simulator in IC-CAP.

The default nominal temperature for SPICE3 is 25°C. To force another nominal temperature, set the TNOM variable to the desired value.

The HPSPICE syntax for the Curtice GaAs MESFET element statement is:

JXXXXXXX ND NG NS MNAME

where:

JXXXXXXX	indicates Curtice MESFET device name (any name that begins with J)
ND	indicates drain node number
NG	indicates gate node number
NS	indicates source node number
MNAME	indicates model name

An example of the Curtice GaAs MESFET device model call is:

 J2 1 2 3 CMES 

The HPSPICE syntax for the .MODEL definition is

.MODEL MNAME RCAY TYPE PNAME1=PVAL1 PNAME2=PVAL2 ...

where:

MNAME	indicates model name
RCAY	key word specifying a GaAs MESFET model
TYPE	indicates NJF (N-channel MESFET) or PJF (P-channel MESFET)
PNAME#	indicates Curtice GaAs MESFET parameter name
PVAL#	indicates parameter value of PNAME#

The parameter MODEL in the .MODEL description must be set:

MODEL = 1 indicates Curtice level 1 quadratic model

MODEL = 2 indicates Curtice level 2 cubic model
