近年來隨著因惡性腫瘤而死亡的人數節節攀升，用於檢測腫瘤的X光影像系統越發重要。本論文的研究目的是設計醫療用X光影像系統的讀出電路與驅動電路，系統的像素架構採用清大范森雄博士提出之特殊架構，此架構能有效降低漏電流，適合應用於大面積的醫療影像，論文中的讀出電路以及驅動電路是針對此像素架構進行設計。藉由驅動電路與讀出電路來控制像素架構，使其操作於曝光狀態，接著由驅動電路選擇欲讀出的像素將像素中儲存的光訊號讀出，經過消除偏移量與放大的處理後供給後續電路處理。
讀出電路晶片以TSMC 0.35μm CMOS製程實現，晶片面積為1.643mm×1.282 mm，讀出電路中包括電荷放大器、相關二次取樣電路與時脈控制電路；驅動電路晶片以TSMC 0.25μm HV CMOS製程實現，晶片面積為0.391mm×0.615 mm，驅動電路中包括移位暫存器與高壓電位轉移電路。量測時輸出動態範圍可達77.45dB，與現行產品規格相當。

Because the number of people who died from cancer was increasing in recent years, X-ray imaging system used to detect tumors has become more and more important. The purpose of this thesis is to design the readout circuit and the driving circuit for an -Si medical X-ray imaging system. The pixel structure in this system was proposed by Dr. Sen-Shyong Fann. This pixel structure was claimed to be able to reduce leakage current, which is especially suitable for large area medical imaging. The readout circuit and the driving circuit of this thesis were designed for the arrays with this pixel structure. The readout circuit can read out the signal stored in the pixel and can cancel the offset caused by the pixel structure.
The readout circuit chip was fabricated in TSMC 0.35μm CMOS process .The chip area is 1.643mm × 1.282 mm. The readout circuit includes charge amplifiers, correlated double sampling circuits, and a clock control circuit. The driving circuit chip was fabricated in TSMC 0.25μm HV CMOS process. The chip area is 0.615mm × 0.391 mm. The driving circuit includes shift registers and HV level-shift circuits. The input dynamic range of the readout circuit can reach 77.45dB, which is quite similar to the specifications of current products.
