Figure 3: Simulation Results
Any nonlinear resistance can be expressed as a nonlinear conductance by inverting the transfer function.
Sometimes, however, it is convenient to implement it directly. This can be done by noting that a resistor is
a current-controlled voltage source. For example,
ERES A 4a VALUE = {I(VSENSE)*{10-1}}
VSENSE 4a B
Where A and B represents the positive and negative terminal nodes of V8.
This represents a linear resistor with a value of 1 kilo-ohm. VSENSE is needed to measure the current
through ERES.
Figure 4: Linear Resistor
A quadratic resistor is then:
ERES A 4a VALUE = {PWRS(I(VSENSE),2)*{10-1}}
VSENSE 4a B
Where A and B represents the positive and negative terminal nodes of V12.
