Sensor signal processing arrangement - adjusts transfer function coefficients to match measure sensor characteristics, correct various noise sources

摘要

A sensor signal processing arrangement performs analogue processing of measurement signals to produce an output parameter related to a reference parameter by a transfer function formed by the ratio of combinations of the measurement effects dependent on physical parameters and an effect dependent on physical and noise parameters. The transfer function coeffts. are adjusted to achieve the desired transfer function according to the measurement sensor characteristics. USE/ADVANTAGE - Esp. suitable for quantised charge transfer processing with charge balancing using switch-capacitor structures. The effect of several noise sources and measurement parameter to measurement effect relationship errors are corrected.
