More Information
Summary:A CMOS concentration of tea polyphenols converter is newly used for sensing the concentration of the polyphenols applications. The proposed converter can transform the concentration of tea polyphenols into frequency linearly. Through the frequency, the concentration of the tea polyphenols could be swiftly and easily attained. Besides, the design of a multistage relaxation oscillator is innovatively investigated in order to provide higher sensitivity for measurements of tea polyphenols. The input range of the proposed converter was 0.1 to 2.2 V, the corresponding range of output frequency was 3.37 to 20.9 MHz. The sensitivities of the proposed converter was 8.34 MHz/V. The proposed chip could be used for sensing the concentration of tea polyphenols applications.
