Temperature dependence of Inductor resistance (Read 4458 times)

mjh New Member Offline Posts: 1	Temperature dependence of Inductor resistance Aug 24^th, 2004, 9:23am Is there any way to add temperature dependence to the inductor resistance created by the Spectre Inductor Model ? I have created many inductor models with the Spectre Inductor Modeler but now need to modify the temperature dependence of the resistance. Thanks.

Simply make r a function of the parameter "temp". For example (for convenience I put the inductor inside an inline subckt - didn't pass the temperature dependent parameters for inductance to avoid it getting cluttered in this example):

Code:

inline subckt myind (n1 n2)
  parameters r=0 l=0 rtc1=0 rtc2=0
  myind (n1 n2) inductor l=l r=r*(1+rtc1*(temp-tnom)+rtc2*((temp-tnom)**2))
ends myind

l1 (ind 0) myind l=1u r=10 rtc1=0.1

Andrew.
