Abstract
Two sets of the DC voltages are determined from among sets of DC voltages. At a first temperature, a first voltage of one of the two sets and a first voltage of the other one of the two sets surround a detection voltage that varies substantially proportionally to temperature. The detection voltage is compared with a second voltage of one of the two sets.
Claims24
A method comprising:
- determining two sets of DC voltages from among a plurality of sets of DC voltages such that, at a first temperature, a first voltage of one of the two sets and a first voltage of the other one of the two sets surround a detection voltage that varies substantially proportionally to temperature;
- and
- comparing the detection voltage with a second voltage of one of the two sets.
A method comprising:
- determining two sets of DC voltages from among a plurality of sets of DC voltages, each set of the plurality of sets of DC voltages having a first voltage, a second voltage, and a third voltage, wherein the first voltage of one of the two sets and the first voltage of the other one of the two sets surround a detection voltage that varies substantially proportionately to temperature at a first temperature;
- comparing the detection voltage with a fourth DC voltage that is between the second voltage and the third voltage of the two sets;
- and
- based on a result of the comparing, comparing the detection voltage with either the second voltage or the third voltage of one of the two sets.
