A temperature sensor includes a constant current source and a transistor stack connected to the constant current source. The transistor stack includes a first transistor having a base connected to the constant current source and a collector coupled to a supply voltage. The collector of the first transistor is electrically isolated from the base of the first transistor. The transistor stack includes a second transistor connected to the first transistor. The second transistor has a collector connected to an emitter of the first transistor and has a base connected to the collector of the second transistor. The transistor stack includes an output node disposed between the constant current source and the base of the first transistor. A voltage of the output node is indicative of a temperature.
