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.

App note: What is a digital transistor?

See the simple composition of a digital transistor, app note from ROHM Semiconductors. Link here

A digital transistor is a bipolar transistor that integrates resistors. Bipolar operation tends to become unstable if the input (Base) is connected directly to the output terminal of an IC for voltage control. Inserting a resistor at the Base stabilizes operation.
