摘　　要：Using native CMOS technology,EDA tool,and adopting full-custom design methodology,a laser diode driver for the use of STM-1 and STM-4 optical access network,is realized by CSMC-HJ 0.6μm CMOS technology to modulate laser diodes at 155Mb/s (STM-1),622Mb/s (STM-4) with adjustable modulation current from 0 to 50mA for an equivalent 50Ω load.The maximum modulation voltage is over 2.5V pp corresponding to a 3V DC bias for output stage.The time range of rise and fall from 360ps to 471ps is measured from the output voltage pulse.The RMS jitter is no more than 30ps for four bit rates.The power consumption is less than 410mW under a power supply voltage of 5V.According to the experimental results,the laser diode driver achieves the same level as their counterparts worldwide.基于国内的CMOS技术和EDA工具以及全定制的设计方法 ,采用无锡华晶上华 (CSMC HJ) 0 6 μmCMOS技术实现了可工作于 15 5Mb/s、6 2 2Mb/s的激光驱动器 .该激光驱动器在 5 0Ω负载上输出电流摆幅从 0到 5 0mA可调 .在输出级 3V直流偏置时最大输出电压摆幅可达 2 5Vpp.输出电压脉冲的上升、下降时间分别小于 471ps和 44 4ps.四个工作速率下均方根抖动都小于 30ps.电路在 5V单电源供电时功耗小于 410mW .芯片测试结果表明 ,该激光驱动器达到了世界同类集成电路的水平 .
