This paper proposes a complementary metal–oxide–semiconductor (CMOS) digitized gas transducer with noise shaping for CO2 concentration monitoring applications. The proposed chip is attractive, because, when combined with various CO2 sensors, it can monitor the present CO2 concentration and then quickly communicate with controllers or computers. The output format of the proposed chip is a type of pulse...
In this paper, a calibrated transducer CMOS circuit for water turbidity monitoring is proposed. The output signal is a pulse stream. It can be easily broadcast over various digital transmission media. In addition, the proposed calibration method can reduce nonlinear errors arising from turbidity sensors. The turbidity of 8–1011 nephelometric turbidity units corresponded to the output frequency range...
