Abstract
A sensor circuit includes a bandgap reference circuit (BGREF) that produces two outputs, a temperature dependent output and a reference voltage, which does not change with temperature. The temperature dependent output includes a PTAT (proportional to absolute temperature, rising with increased temperature) portion and a CTAT (complementary to absolute temperature, falling with increased temperature) portion. Circuitry is provided that calculates the reference voltage by adding the PTAT portion and a divided version of the CTAT portion in which the CTAT portion has been divided by a divisor.
