Parameters: R: Reference resistance (default value = 1 Ohm) Tnom: Reference temperature (default value = 300.15 oK) TR1: Linear temperature variation coefficient (default value = 0 1/oK) TR2: Quadratic temperature variation coefficient (default value = 0 1/oK2) Area: Relative area occupied by resistor (default value = 1)
Equations:
DTemp = e2 - Tnom
Rval = R*(1 + TR1*DTemp + TR2*DTemp*DTemp)/Area
e1 = Rval*f1
f2 = (e1/e2)*f1
