本論文，提出了一個對製程漂移具低靈敏度及改善過衝性能之高速且大電流雷射二極體驅動電路，此設計主要應用於DVD播放機。在大電流和高速度輸出的雷射二極體驅動電路中，為了提高信號完整性，以及使電路受製程、電壓、溫度和其他環境的影響可以減少。因此，我們針對文獻[9]所提出的組合開關模式雷射二極體驅動電路架構(Combination Switch Mode Laser Diode Driver Architecture)做出修改。所以我們提出源衰退型組合開關模式雷射二極體驅動電路架構。
此外如向上過衝電流(Overshoot)、向下過衝電流(Undershoot)、上升時間(Rising Time)和下降時間(Falling Time)是所必須考慮的問題。經由模擬結果顯示，在電路進行放電時，速度稍微變慢，但在向上過衝電流(Overshoot)和向下過衝電流(Undershoot)卻是有顯著的改善。最後提出源衰退型與改善過衝性能組合開關模式雷射二極體驅動電路架構(Source Degeneration Type with Improve Overshoot Performance (CSM) Laser Diode Driver Architecture)。使用TSMC 0.35um 5V的製程，以HSPICE軟體來進行電路模擬和分析，並以Cadence Virtuoso Layout Editor完成電路佈局的工作。而晶片總面積為1.074×0.948mm2。

Here, proposed a high speed and large current laser diode driving circuit with low sensitivity to process variation and improvement on overshoot performance, mostly applied in the DVD player. In the large current and high speed output laser diode driver circuit, in order to improve signal integrity, and reduce the impacts caused by temperature, voltage, process and environmental. Therefore, modifications on the Combination Switch Mode Laser Diode Driver Architecture [9]was made. So we proposed the Source Degeneration Type Combination Switch Mode Laser Diode Driver Architecture.
Furthermore, topics such as overshoot, undershoot, rising time and falling time are necessary to be considered. The simulation results show that the output current turned slightly slower in speed, whereas the performance in overshoot and undershoot are significantly improved. Finally, we proposed the Source Degeneration Type with Improve Overshoot Performance Laser Diode Driver Architecture. The circuit has been implemented in 0.35um 5V CMOS process and simulated by HSPICE. And the Cadence Virtuoso Layout Editor to complete the circuit layout of the work. The overall chip area is 1.074*0.948mm2.
