and 100µA, the change in the measured voltage due to
series resistance is:
Since 1°C corresponds to 198.6µV, series resistance
contributes a temperature offset of:

Assume that the sensing diode being measured has a
series resistance of 3 . The series resistance con-
tributes a temperature offset of:
The effects of the ideality factor and series resistance
are additive. If the diode has an ideality factor of 1.002
and series resistance of 3 , the total offset can be cal-
culated by adding error due to series resistance with
error due to ideality factor:
for a diode temperature of +85°C.
