本論文提出適用於穿戴式裝置之反向V型曲率校正電路之能隙參考電壓電路與應用於鋰電池充電之高精準度溫度感測晶片。能隙參考電壓電路使用反向V型曲率校正技術，在寬廣的溫度範圍(-40℃至140℃)操作下，減少參考電壓對溫度變化的變異，所獲得的溫度係數為0.778 ppm/°C，相較於未補償前之能隙參考電壓電路的溫度係數，具有70.2%的改善幅度。
本論文也提出應用於鋰電池充電之高精準度溫度感測晶片來提高鋰電池充電的安全性，且延長鋰電池使用壽命。應用於鋰電池充電之高精準度溫度感測晶片分成三種充電模式感測訊號，當溫度在8.2℃至47.3℃產生正常充電模式感測訊號；當溫度在1.5℃至8.2℃和47.3℃至66℃時產生降低充電電壓電流模式感測訊號；當溫度在1.5℃以下和66℃以上產生禁止充電模式感測訊號，本論文的電路設計與晶片製作皆使用TSMC 0.18-μm 1P6M CMOS製程實現。

The proposed bandgap reference with an inverted v-curve correction circuit for wearable devices and a high-precision temperature sensing chip for lithium battery charging. The bandgap reference reduces the temperature drift of the reference voltage by using an inverted v-curve correction technology in a wide temperature range. The temperature coefficient is 0.778 ppm/°C that has a 70.2 % improvement compared with the uncompensated bandgap reference temperature coefficient.
The proposed a high-precision temperature sensing chip for lithium battery charging to improve the safety of lithium battery charging and extend the operation life of lithium battery. A high-precision temperature sensor chip used for lithium battery charging is divided into three charging modes sensing signals. The lithium battery performs the normal charging mode sensing signals when the temperature is between 8.2 ℃ and 47.3 ℃；the lithium battery performs lower charging voltage and lower charging current mode sensing signals when the temperature is 1.5 ℃ to 8.2 ℃ or 47.3 ℃ to 66 ℃；the lithium battery performs disable charging mode sensing signals when the temperature is below to 1.5 ℃ or above on 66 ℃. All circuit were designed and fabricated by using a standard TSMC 0.18-μm 1P6M CMOS technology.
