Tool/software:
I would like to ask about the details of the circuit design of the temperature sensor:
The first question is when selecting a remote diode sensor, most designs use NPN or PNP transistors, why not just use ordinary diodes? Both are based on the relationship between PN junction forward voltage drop and temperature.
The second question is why the base and collector connections D+ and D − of the transistor are not chosen in the design, but the base and emitter are generally chosen?
