The diode temp is measured by a diode on the die. The diode measurement works because the forward voltage drop (usually expressed as 0.6V) changes slightly with temp.

I’ve been using diodes as temperature sensors in three projects over the last year: one is a coffee roaster that brings the beans up to 220 °C in hot air, another is a reflow hotplate that tops ...

Measuring temperature Because die temperature is a critical parameter, some devices incorporate a means to allow you to measure it—normally, a diode or a diode-connected transistor near the hot spot ...

Texas Instruments has announced an integrated +/-1C maximum remote junction temperature sensor and local temperature sensor, designed to monitor thermal diodes found in CPUs, microprocessors, graphics ...

For reduced power, the sensor can be put into sleep mode, reducing consumption to 10 µA. In a MSOP-8 package, price is $1.75 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.

The transconductance characteristics of a MOS transistor realized in a submicron technology have the zero-temperature coefficient (ZTC) bias point. The gate-source voltage of such transistor is ...
