Abstract
A nitrogen-oxide (NOx) sensor control system includes a NOx sensor analog front-end, a temperature sensor analog front-end, and a processing system. The NOx sensor analog front-end is adapted to receive analog NOx sensor signals from a NOx sensor and is configured to convert the analog NOx sensor signals to digital NOx sensor signals. The temperature sensor analog front-end is adapted to receive analog temperature sensor signals from a temperature sensor and is configured to convert the analog temperature sensor signals to digital temperature sensor signals. The processing system is coupled to receive the digital NOx sensor signals and the digital temperature sensor signals and is configured, in response thereto, to: supply the digital NOx sensor signals to an external system, and control a flow of current to a heater element in the NOx sensor.
