This project is to show how diodes can be used to tell if there a temperature difference using two diodes. The equation to find the voltage across the diode has temperature as one the dependent variables, and it is pretty reliable. The reason why resistors are not used because the TCR, or the variable that measures how much the resistance changes due to temperature, is because it is a linear term, instead as in the voltage across diode where the temperature affects the voltage exponentially and reliable. The TCR of an resistor also can be a positive number or a negative number, which means that a as tool to see if there is a temperature differential. This project idea was taken from the wiki of Analog Circuits, as one of their suggested projects. Fig 1. Circuit Schematic of the Temperature Differential Voltage Circuit I used the circuit diagram proved by the wiki of Analog Devices, as shown by Fig 1, with the voltage source being the power supply that was made as the class pro...
