Appendix A - Thermal Diode Calculations 81

31993A-1 September 2004 AMD Sempron™ Processor Model 10 Data Sheet

AMD Preliminary Information

The formulas in Equation (3) and Equation (4) can be used to

calculate the temperature offset for temperature sensors that

do not employ series resistance cancellation. The result is

added to the value measured by the temperature sensor.

Contact the vendor of the temperature sensor being used for

the value of n

f,TS

. Refer to the document, On-Die Thermal Diode

Characterization, order# 25443, for further details.

Equation (3) shows the equation for calculating the lumped

ideality factor (n

f, lumped

) in sensors that do not employ series

resistance cancellation.

Equation (4) shows the equation for calculating temperature

offset (T

offset

) in sensors that do not employ series resistance

cancellation.

Equation (5) is the temperature offset for temperature sensors

that utilize series resistance cancellation. Add the result to the

value measured by the temperature sensor. Note that the value

of n

f,TS

in Equation (5) may not equal the value used in

Equation (4).
