Polynomial Current Controlled Current Source (pcccs)
A vector of coefficients specifies the polynomial function that defines the relationship between the output current and the controlling currents. You must specify at least one coefficient.
This device is supported within altergroups.
For a polynomial in M variables a1, a2, ... am, the polynomial function F(a0,a1,...,am) is given by
F = c0 + c1 * a1 + c2 * a2 + ...
+ c(m+1) * a1^2 + c(m+2) * a1 * a2 +...
+ c(2m+1) * a2^2 + c(2m+2) * a2 * a3 +...
where the cs are coefficients of the polynomial terms.

probes=[...]
|
Devices through which the controlling currents flow.
|
|
mprobes=[...]
|
The mprobes function the same as probes except that they will divide the input currents by the mfactor.
|
|

|
Indexes of the probe ports through which the controlling currents flow.
|
|
coeffs=[...]
|
Polynomial coefficients. At least one must be given.

file
|
File that contains nonzero polynomial coefficients.
|
|
min (A)
|
Minimum output current.
|
|
max (A)
|
Maximum output current.
|
|
abs=off
|
Absolute output current. Possible values are off or on.
