Linear CCCS Netlist Format

The format for a linear current-controlled current source (CCCS) is:

Fxxxx out+ out- [CCCS] vin [GAIN=]gain

[MAX=val] [MIN=val] [M=val]

[SCALE=val] [TC1=val] [TC2=val] [ABS=0|1]

out+ is the positive node and out- is the negative node of the current source. The entry CCCS is the default for the F element type. vin is a voltage source through which the control current flows. The input voltage source must be defined elsewhere in the netlist.

The functional equation for the linear VCCS is:

I(out+, out-) = GAIN ´ I(vin) ´ SCALE ´ M ´ (1 + DT ´ TC1 + DT² ´ TC2)

If the result is less than MIN,

I(out+, out-) = MIN

If the result is greater than MAX,

I(out+, out-) = MAX

**Linear CCCS Instance Parameters**
Parameter	Description	Unit	Default
ABS	1 = Output is an absolute value	None	0
GAIN	Current gain	None	1.0
M	Number of elements in parallel	None	1.0
MAX	Maximum output current	Amp	None
MIN	Minimum output current	Amp	None
SCALE	Multiplier for current	None	1.0
TC1	Linear (1st-order) temperature coefficient	°K^-1	0.0
TC2	Quadratic (2nd-order) temperature coefficient	°K^-2	0.0
