摘要：
A biological information sensing circuit and an operating method thereof are disclosed. The biological information sensing circuit is coupled to a micro-controller and a plurality of electrodes respectively. The biological information sensing circuit includes a power supply module and an electrode state detecting module. The power supply module is coupled to the micro-controller and receives a wake-up signal from the micro-controller. The electrode state detecting module is coupled to the electrodes and the power supply module respectively. The electrode state detecting module includes a switching unit. The switching unit is coupled to an electrode of the switching unit, a reference voltage and a ground voltage respectively and switches the electrode to conduct to the reference voltage or the ground voltage according to the wake-up signal.本發明揭露一種生物資訊感測電路及其運作方法。生物資訊感測電路分別耦接微控制器及多個電極。生物資訊感測電路包括供電模組及電極狀態偵測模組。供電模組耦接微控制器，接收來自微控制器的喚醒信號。電極狀態偵測模組分別耦接該些電極及供電模組。電極狀態偵測模組包括切換單元。切換單元分別耦接該些電極中之一電極、參考電壓及接地電壓，根據喚醒信號切換電極導通至參考電壓或接地電壓。
