摘要：
The present invention relates to an optical sensor that may be implanted within a living animal (e.g., a human) and may be used to measure the concentration of an analyte in a medium within the animal. The optical sensor may wirelessly receive and may be capable of bi-directional data communication. The optical sensor may include a semiconductor substrate in which various circuit components, one or more photodectors and/or a light source may be fabricated. The circuit components fabricated in the semiconductor substrate may include a comparator, an analog to digital converter, a temperature transducer, a measurement controller, a rectifier and/or a nonvolatile storage medium. The comparator may output a signal indicative of the difference between the outputs of first and second photodetectors. The measurement controller may receive digitized temperature, photodetector and/or comparator measurements and generate measurement information, which may be wirelessly transmitted from the optical sensor.本發明係關於一種可植入於一有生命的動物(例如,一人類)體內且可用於量測該動物體內之一介質中之一分析物之濃度的光學感測器。該光學感測器可以無線方式接收且可能夠進行雙向資料通信。該光學感測器可包含一半導體基板,其中可製作各種電路組件、一或多個光偵測器及/或一光源。製作於該半導體基板中之該等電路組件可包含一比較器、一類比轉數位轉換器、一溫度傳感器、一量測控制器、一整流器及/或一非揮發性儲存媒體。該比較器可輸出指示第一光偵測器與第二光偵測器之輸出之間之差異之一信號。該量測控制器可接收數位化溫度、光偵測器及/或比較器量測,且產生可自該光學感測器以無線方式傳輸之量測資訊。116‧‧‧半導體基板/矽基板530‧‧‧輸入/輸出電路532‧‧‧量測控制器534‧‧‧類比介面/溫度傳感器536‧‧‧輸入/輸出前端塊538‧‧‧輸入/輸出控制器
