Abstract
Integrating ADC based sensing systems that convert the output of a measurement sensor to a digital value avoid conversion errors caused by sensor temperature variation during the conversion cycle. The systems may either include a primary integrating ADC and a residue ADC, and adjust rate of operation of the ADCs independently according to a sensed temperature of the measurement sensor, or the systems may differentiate an output of the residue ADC, and apply a temperature correction in accordance with the sensed temperature of the sensor to an output of the differentiator, integrate the temperature-corrected output of the differentiator and then combine the result with the output of the primary integrating ADC.
