Diodes As Temperature Sensor

The diodes can also be used as a temperature sensor that is by utilizing the properties of the junction voltage

Also used on an integrated circuit temperature sensor (having an amplifier and compensation circuit in the same chip). Examples of the circuit with a diode as a temperature sensor

Examples of the circuit with a sensor IC

Alternative circuit to convert the current into a voltage to the IC temperature sensor
