  • Abstract
    A smart temperature sensor is accurate to within ±0.1°C (3σ) over the full military temperature range of -55°C to 125°C. This 5× improvement is achieved using DEM, a current-gain independent PTAT bias circuit, and a low-offset ΔΣ ADC combining chopping and CDS. The sensor is fabricated in 0.7μm 2M1P CMOS with 4.5mm2 area and draws 75μA.
