【発明の名称】センサ信号を処理する装置
Document Type and Number:
Japanese Patent JPH04500413
Kind Code:
A
Abstract:
The arrangement serves to process sensor signals furnished by a sensor which when fed with a supply signal in response to the action of a physical measured quantity. The sensor generates a measuring effect representing the dependence of an electrical characteristic quantity on the physical measured quantity. The arrangement also includes a signal processing circuit which operates by the principle of quantized charge transport by means of switch-capacitor structures. The signal processing circuit establishes a charge balance by opposite integration of measuring charge packets dependent on the measuring effect and compensation charge packets independent of the measuring effect and furnishes an analog output signal corresponding to the integration result. The analog output signal also provides a feedback input to the sensor. By this feedback the analog output signal is regulated so that it is proportional to the measurement result.
