Remote temperature measurements have to be linked by some sort of cable to the relevant test instrument. Normally, this is a three-core cable: one core for the signal and the other two for the supply ...
Two papers at the International Solid-state Circuits Conference tackled ultra-low power on-chip temperature sensing, one using an npn transistor and the other by sensing a wire. The npn sensor ...
The Type LM35 temperature sensor from National Semiconductor is very popular for two reasons: it produces an output voltage that is directly proportional to the measured temperature in degrees Celsius ...
