Form this example it should be apparent that the value of n used can be quite important.
Since both I_s and V_T are functions of temperature, the forward i-v characteristic varies with
Temperature as illustrated in Fig. 3.9 At a given constant diode current the voltage drop
Across the diode decreases by approximately 2mV for every 1℃ increase in Temperature.
The change in diode voltage with Temperature has been exploited in the design of electronic
Thermometers.
