Abstract
A CMOS smart temperature sensor with digital output is presented which consumes less than 7¿W. It operates at supply voltages down to 2.2V. The circuit uses substrate bipolars as temperature sensor. Conversion to the digital domain is done by a sigma-delta converter, which makes the circuit highly insensitive to digital interference. In the temperature range from ¿40 to + 120°C, inaccuracy is ±1°C after calibration at two temperatures.
