Abstract:
1. A method of temperature measurement, the method comprising: performing a first ΔVbe measurement of a first temperature of a diode circuit comprising a transistor; subsequently performing a first Vbe measurement of a second temperature of the diode circuit; calculating a temperature difference between the second temperature and the first temperature; if the temperature difference between the second temperature and the first temperature is not greater than a predetermined amount, subsequently and repeatedly performing a second Vbe measurement of a third temperature of the diode circuit for as long as a temperature difference between the third temperature and the first temperature is not greater than the predetermined amount; if the temperature difference between the second temperature and the first temperature is greater than the predetermined amount, performing a second ΔVbe measurement of the second temperature of the diode circuit; and when a temperature difference between the third temperature and the first temperature is greater than the predetermined amount, performing the second ΔVbe measurement of the third temperature of the diode circuit.
