App note: Notes for temperature measurement using forward voltage of PN junction

App note from ROHM Semiconductors about the cautions when measuring temperature from PN Junctions. Link here (PDF)

The forward voltage of a pn junction can be measured to estimate the junction temperature of a semiconductor device. However, correct results may not be obtained if the measurement is performed incorrectly.
