Abstract:
1. A method for resistance compensated temperature measurement, the method comprising: providing a diode connected transistor; applying a first current to the diode connected transistor, wherein a first base-emitter voltage corresponding to the first current is exhibited by the diode connected transistor; applying a second current to the diode connected transistor, wherein a second base-emitter voltage corresponding to the second current is exhibited by the diode connected transistor; applying a third current to the diode connected transistor, wherein a third base-emitter voltage corresponding to the third current is exhibited by the diode connected transistor; applying a fourth current to the diode connected transistor, wherein a fourth base-emitter voltage corresponding to the fourth current is exhibited by the diode connected transistor; and combining the first base-emitter voltage, the second base emitter voltage, the third base-emitter voltage and the fourth base emitter voltage, wherein a resistance error is eliminated.
