Abstract
An apparatus and method are disclosed for temperature measurement that includes performing a first ΔVbe measurement of a first temperature of a diode circuit comprising a transistor and, subsequently, performing a first Vbe measurement of a second temperature of the diode circuit. A temperature difference is calculated between the second temperature and the first temperature. If the temperature difference is not greater than a predetermined amount, a second Vbe measurement of a third temperature of the diode circuit is subsequently performed. If the temperature difference is greater than the predetermined amount, a second ΔVbe measurement of the second temperature of the diode circuit is performed.
