Abstract:
1. A system for measuring temperatures of a device, comprising: a dual diode system comprising a first junction diode and a second junction diode, wherein the first junction diode and the second junction diode are collocated on a first substrate, the dual diode system having (i) a first terminal that is coupled to a first electrode of the first junction diode, wherein the first electrode of the first junction diode has a first polarity, (ii) a second terminal that is coupled to a first electrode of the second junction diode, wherein the first electrode of the second junction diode has the first polarity, and (iii) a third terminal that is coupled to second electrodes of the first and second junction diodes, wherein the second electrodes of the first and second junction diodes have a second polarity that is opposite of the first polarity; a temperature measurement circuit that is located on a second substrate and that is configured to perform a voltage measurement by measuring two voltages that result after successively applying two different currents to a single junction diode through a single terminal, wherein the single junction diode is one of the first junction diode and the second junction diode, and wherein the single terminal is one of the first terminal and the second terminal; and a bias circuit that is configured to bias the third terminal.
