Si p-n junctions are often used as temperature sensors.Draw relevant schematic below and calculate the diode voltage if the temperature is raised by deltaT= 20c above the room temp.

Assume the turn-on voltage for the diode equals 660 mV at room temperature while conducting 10uA current.

please show all steps.

Expert Solution

In the above, Vd=42mv and Vd=50mv. Some authors give Vt as 2mv/°C and some give as 2.5mv/°C. So both answers are absolutely correct and it's upto you to choose which value of Vt.

Do give a like if you like the answer. It'll encourage me to write more quality answers.
