4.7 POLY: Polynomial nonlinear transfer function
4.7.1 Syntax
POLY c0 c1 c2 c3 ...
POLY c0 c1 c2 c3 ... args
4.7.2 Purpose
Defines a transfer function by a one dimensional polynomial.
4.7.3 Comments
For capacitors, this function defines charge as a function of
voltage. For inductors, it defines flux as a function of
current. If you have the coefficients defining capacitance or
inductance, prepending a “0” to the list will turn it into the
correct form for Gnucap.
For fixed sources, it defines voltage or current as a polynomial
function of time.
The transfer function is defined by:
out = c0 + (c1*in) + (c2*in^2) + ....
4.7.4 Parameters
- MIN = x
- Minimum output value (clipping).
(Default = -infinity.)
- MAX = x
- Maximum output value (clipping).
(Default = infinity)
- ABS
- Absolute value, truth value. (Default = false). If
set to true, the result will be always positive.
