Patent ID: 7018095

Claim:
An apparatus comprising: an integrated circuit (IC) having a first, second, and third IC terminal; a first diode to measure a first temperature at a first location on the IC, wherein an anode terminal of the first diode is coupled to the first IC terminal and a cathode terminal of the first diode is coupled to the second IC terminal; a second diode to measure a second temperature at a second location on the IC, which is spaced apart from the first location, wherein the second diode is coupled between the first and second IC terminals in an opposite polarity of the first diode; a third diode to measure a third temperature at a third location on the IC, which is spaced apart from the first and second locations, wherein the anode terminal of the third diode is coupled to the second IC terminal and a cathode terminal of the third diode is coupled to the third IC terminal; and a fourth diode to measure a fourth temperature at a fourth location on the IC, which is spaced apart from the first, second, and third locations, wherein the fourth diode is coupled between the second and third IC terminals in the opposite polarity of the third diode.
