血糖濃度感測讀取電路之設計與實現

由於現代人工作繁忙又加上人口高齡化問題，導致缺乏運動習慣、飲食不均衡、對於健康飲食的忽略、水補充不足等等因素，增加了血糖濃稠度提高的可能性，此結果恐導致糖尿病等其他慢性相關疾病的產生。本論文提出一項利用生物感測器感測血糖濃度之讀取電路，使用於識別不同的血糖濃度，進而了解到人體的基本身體狀況，在改善健康狀況上更能對症下藥。血糖濃度的改變來自於血糖，經過生物測試得到血糖濃度對於阻抗之表現，得到此論文研究的基礎，本電路設計採用TSMC0.18μm1P6M CMOS標準製程所實現。此讀取電路可視為反相放大器，感測器得到值分別歸類為異常濃度、正常濃度、濃度過高狀態。感測器輸出的值為脈波振幅，使用High Pass Filter - Clock得出的訊號減掉感測訊號得到感測結果。晶片整體面積為0.410×0.320mm 2，功率消耗為1.76mW。

Due to the busy work of modern people and the problem of aging population, factors such as lack of exercise habits, unbalanced diet, neglect of healthy diet, insufficient water supplement, etc., increase the possibility of blood glucose concentration, which may lead to diabetes. And other chronic related diseases. This thesis proposes a readout circuit that uses a biosensor to sense blood glucose concentration, which is used to identify different blood glucose concentrations, and then to understand the basic physical condition of the human body, which is more effective in improving health conditions. The change of blood glucose concentration comes from blood glucose, and the performance of blood glucose concentration on impedance is obtained through biological test, which is the basis of the research in this thesis. This circuit is designed using TSMC0.18μm1P6M CMOS standard process. This readout circuit can be regarded as an inverting amplifier, and the values obtained by the sensors are classified into abnormal concentration, normal concentration, and high concentration state, respectively. The output value of the sensor is a pulse wave amplitude. The signal obtained by using the High Pass Filter-Clock is subtracted from the sensing signal to obtain the sensing result. The overall area of the chip is 0.410 × 0.320 mm² and the power consumption is 1.76 mW.
