臺灣博碩士論文加值系統

近年來，隨著人們對於影音品質的要求提昇，更清晰的影像，更逼真的音效，更順暢的畫面，大容量的光碟片與高速的光纖通訊也因應而生，而雷射二極體為不可或缺的重要角色。
在本篇論文中主要探討一個大電流的高速雷射二極體驅動電路應用於 DVD/CD 等光學儲存碟片存取。基於之前提出的Source-Follower Mode 架構，加以改進其電路reaction time、 rising/falling time、 overshoot/undershoot 、corner case (TT FF SS FS SF)來得到更好的效能。
我們使用TSMC 5V 0.35-μm CMOS製程來實現我們的晶片。晶片面積為1.070×1.376mm2，必v約為1000 mW。

Laser Diode Driver (LDD) can be find in many applications optical disks such as CD, DVD, Blue-ray disc, and fiber-optical communication….etc. Today the data is bigger and more complex than before. Therefore, a high-speed LDD is very important with high capacity optical store devices and high-speed optical communication. In this paper, we focus on design of high speed and large current Laser Diode Driver for DVD/CD Read/Write. We main target to enhance rising time, falling time, reaction time, overshoot/Undershoot (<10%) and corner case (FF SS FS SF).
The design of high-speed Laser Diode Driver with reaction time was implemented in a 5V 0.35-μm CMOS technology. The overall chip area is 1.070×1.376 mm2 and the power consumption is 1000 mW.
