Abstract: A temperature sensor module with an integrated lid structure for spurious IR-cancellation is disclosed. An improved temperature sensor module that allows detection of a maximum of the relevant IR-radiation from an object's surface of interest as well as generation of additional information about parasitic or spurious IR-radiation that distort the relevant thermal signal in order to enable a cancellation of interfering thermal signal portions is presented. The temperature sensor module includes a temperature sensing element, a sensor-interface control integrated circuit, whereas the temperature sensing element is coupled to the sensor-interface control IC, and a lid structure and a sensor packaging both defining a field of view of the temperature sensor module, wherein the lid structure is formed by a substrate comprising a second integrated temperature sensor connected to the sensor-interface control IC or an external connected processing unit.

Abstract: A method and arrangement for setting an effective resolution of an output signal in an incremental delta-sigma analog-to-digital conversion by an incremental delta-sigma analog-to-digital converter, includes feeding a difference between an input signal and a reference voltage signal formed in a feedback branch to a first integrator. Safeguarding the stability of multi-stage incremental delta-sigma analog-to-digital converters for large input signal ranges and not requiring direct damping of the input signal, such that a direct SNR impairment with regard to the ADC-inherent noise sources can be avoided, is achieved by a virtual reference voltage in the feedback branch of the incremental delta-sigma analog-to-digital converter. The reference voltage signal is adapted to a changing input signal range by a settable reference capacitance and a clock cycle number dependent thereon is set.
