摘要： Various examples are directed to systems and methods for managing a sensor. A measurement system may receive, from a host device, a first register map describing a first configuration of a measurement system. The first configuration may be associated with a first sensor. The measurement system may compare the first register map to an error rule set indicating inconsistent register map arrangements. After comparing the first register map to the error rule set, the measurement system may configure a switch matrix of the measurement system to sample the first sensor according to the first configuration of the measurement system. The measurement system may receive a plurality of samples from a first sensor and generate first digital measurement data based at least in part on the plurality of samples.

摘要： Various examples are directed to methods and system of managing a sensor. A measurement system may receive from the host device, a first register map describing a first configuration of the measurement system for the first sensor. The first configuration may indicate a first measurement frequency for the first sensor. The measurement system may configure a switch matrix to provide a first excitation signal to the first sensor. The measurement system may configure the switch matrix to connect an analog-to-digital converter (ADC) of the measurement system to the first sensor. The measurement system may sample a first raw sensor signal from the first sensor with the ADC at a first measurement frequency described by the first configuration. The measurement system may generate first digital measurement data based at least in part on the first raw sensor signal and send the first digital measurement data to the host device.

摘要： Techniques that allow application of noise-shaped dither without applying dither at sampling, resulting in the analog-to-digital converter (ADC) circuit advantageously being balanced during acquisition. Balancing the ADC circuit at acquisition can reduce the risk of sampling digital interferences that can couple in through the references or substrates.

摘要： Techniques to increase a data throughput rate of a filter circuit by preloading selectable memory circuits of the filter circuit with reference data, sampling input data at an input of the filter circuit, combining the sampled input data with the preloaded reference data, and generating a filter output based on the combined sampled input data and preloaded reference data.
