In this paper, a CMOS chlorophyll concentration detector based on organic chlorophyll battery for measuring vegetable chlorophyll concentration is newly proposed. The organic chlorophyll battery and analog processing circuits are compactly and robustly cooperated. Comparing with previous works, the proposed chlorophyll concentration detector can be possibly easy and low-cost realized by users. All the functions and performance of the proposed chlorophyll concentration detector for measuring vegetable chlorophyll concentration are successfully tested and proven through measurements. The measured chlorophyll concentration of spinach ranges from 25 to 475 mu mol/m(2), and the corresponding output frequency range is 599.2 kHz-1.174 MHz. The proposed chlorophyll concentration detector is suitable for devices measuring vegetable chlorophyll concentration.
