Voltage-Controlled Voltage Source, Linear

Linear VCVS Netlist Format

The format for a linear voltage-controlled voltage source (VCVS) is:

Exxxx out+ out- [VCVS] in+ in- [GAIN=]gain

[MAX=val] [MIN=val]

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

out+ is the positive node and out- is the negative node of the voltage source. The entry VCVS is the default for the E element type. in+ and in- are the positive and negative nodes for the control voltage.

The functional equation for the linear VCVS is:

V(out+) - V(out-) = GAIN ´ (V(in+) -V(in-)) ´ SCALE ´ (1 + DT ´ (TC1 + DT ´ TC2))

If the result is less than MIN,

V(out+) - V(out-) = MIN

If the result is greater than MAX,

V(out+) - V(out-) = MAX

**Linear VCVS Instance Parameters**
Parameter	Description	Unit	Default
ABS	1 = Output is an absolute value	None	0
GAIN	Voltage gain (multiplier applied to control voltage)	None	1.0
MAX	Maximum output voltage	Volt	None
MIN	Minimum output voltage	Volt	None
SCALE	Multiplier for voltage	None	1.0
TC1	Linear (1st-order) temperature coefficient	°K^-1	0.0
TC2	Quadratic (2nd-order) temperature coefficient	°K^-2	0.0
