中文摘要 | 本文提出一個適用於光纖通訊發射器的CMOS雷射二極體驅動電路,使用TSMC 0.35um 1P4M的CMOS(互補式金屬氧化物半導體)製程參數來作模擬,其資料傳輸速率(data rates)可達4 Gb/s。該驅動電路包含三個主要模組區塊:PECL to CMOS邏輯電路、調變電流產生電路(modulation current-generator circuit)、以及偏壓電流產生電路(bias current-generator circuit)。我們額外加入pulse shaping stage的電路來達到穩定電流的作用,並且避免掉輸出電流overshoot與undershoot的現象。此外我們也顧及bond wire的負載效應,連同雷射二極體的模型一同考慮。模擬結果係針對雷射二極體驅動電路在不同的輸入電壓範圍、不同的調變電流大小,以及不同的資料傳輸速率下所作的分析比較。模擬的結果,顯示該我們的雷射二極體驅動電路具有不錯的效能。 |
英文摘要 | In this study, a 4 Gb/s integrated laser driver is designed for an optical transmitter by using TSMC 0.35um 1P4M CMOS (complementary metal-oxide-semiconductor) technology. The proposed laser driver includes three blocks: PECL to CMOS logic circuit, modulation current-generator circuit and bias current-generator circuit. In the design a pulse-shaping stage is used to achieve a steady DC current and avoid an output current to overshoot and undershoot. Furthermore, laser diode models that include a bond-wire loading effect are considered. The simulation results are illustrated in an eye diagram for comparisons. The laser driver is simulated with regard to different input swing, different modulation current and different data rate. The simulation results indicate that our laser driver achieves a brilliant performance. |
