Abstract
An apparatus includes a temperature measurement circuit. The temperature measurement circuit includes a bandgap circuit including an amplifier having an offset voltage that is compensated by using a set of trimming bits. The bandgap circuit provides first and second voltages related to a temperature to be measured. The temperature measurement circuit further includes a measuring circuit coupled to receive the first and second voltages. The measuring circuit further includes a comparator coupled to receive the first and second voltages, wherein the measuring circuit derives a temperature measurement from the first and second voltages.
