MESFETs

General Form:
zname nd ng ns modname [parameters ...]

Parameter Name Description
off Device is initially nonconducting, for circuit convergence assistance.
area=val Scale factor that multiplies all currents and other values, effectively modifying the MESFET area.
ic=vds,vgs The initial voltages (initial condition) for transient analysis.
icvds=vds The initial vds (initial condition) for transient analysis.
icvgs=vgs The initial vgs (initial condition) for transient analysis.

Examples:
z1 7 2 3 zm1 off
zout 21 4 16 zmod1 area=5

The nd, ng, and ns are the drain, gate, and source nodes, respectively. The modname is the model name, area specifies the area factor, and off indicates an initial condition of the device for dc analysis. If the area factor is omitted, a value of 1.0 is assumed. The initial condition specified using ic or alternatively icvds and icvgs are intended for use with the uic option in transient analysis, when a transient analysis is desired starting from other than the quiescent operating point. The .ic line provides another way to set initial conditions.
