Abstract:
An integrated circuit includes a device identification circuit and a temperature sensor diode connected in parallel from a common node. The device identification circuit includes a resistor connected to a diode-connected transistor. The device identification circuit and the temperature sensor diode are adapted to not be simultaneously operating in an ON state. A first voltage is applied to the common node to place the device identification circuit in an ON state and place the temperature sensor diode in an OFF state to identify the integrated circuit. A second voltage is applied to the common node to place the device identification circuit in an OFF state and place the temperature sensor diode in an ON state to determine a temperature of the integrated circuit.
