摘　　要：一种应用于高速光纤通讯系统的激光二极管 /调制器的单片集成驱动电路已开发成功。该电路的制造使用了 0 2 μmPHEMT工艺 ,它的工作信号带宽超过 12GHz。在 12Gb/s速率下测得了摆幅峰峰值为 3 4V的输出信号眼图。基于实验结果 ,我们判断该电路的最大工作速率超过 2 4Gb/s。该驱动器电路使用单电源 -4 5V供电 ,功耗小于 1 8W。An integrated laser/modulator driver for high-speed optical fiber communication systems has been developed. The integrated circuit was fabricated in a 0.2μm gate length AlGaAs/InGaAs/GaAs pseudomorphic high electon mobility transistors(PHEMTs) technology with thin film resistors, metal-insulator-metal(MIM) capacitors and spiral inductors. Its large signal bandwidth is over 12GHz. The eye diagrams were measured at bit rate up to 12Gb/s with an output voltage swing of 3.4 V p-p at single end of output. With measured characteristics we estimate that the driver IC can operate at bit rate of higher than 24Gb/s. The power consumption is less than 1.8W using a simgle supply voltage of -4.5V.
