A smart temperature sensor is accurate to within /spl plusmn/0.1/spl deg/C (3/spl sigma/) over the full military temperature range of -55/spl deg/C to 125/spl deg/C. This 5/spl times/ improvement is achieved using DEM, a current-gain independent PTAT bias circuit, and a low-offset /spl Delta//spl Sigma/ ADC combining chopping and CDS. The sensor is fabricated in 0.7/spl mu/m 2M1P CMOS with 4.5mm/sup 2/ area and draws 75/spl mu/A.
