本文提出了一种面向高密度集成的多通道Mach-Zehnder调制器的驱动器电路结构
单通道驱动器包含信号均衡器、时钟树模块、时钟延时控制模块和输出摆幅控制模块等电路
支持各通道25 GHz高速差分时钟延时与驱动器输出摆幅的独立可调
以及最高25 Gbps的NRZ数字信号传输.基于TowerJazz0.18 μm SiGe BiCMOS工艺
完成了6通道驱动器的芯片设计.仿真结果表明
单通道带宽达到17.2 GHz
最大差分输出摆幅为3 Vppd
Jitter约为8.9 ps
在2.3/3.6V双电源供电下单通道功耗约为646.9 mW.
A design of multi-channel Mach-Zehnder modulator driver aiming at high-density integration is proposed in this paper
the single-channel circuits consists of signal equalizer
clock tree
delay control module
output swing control module and other amplifying components
supporting delay-tunable 25GHz high-speed differential clock signals
swing-tunable differential outputs
and up to 25 Gbps NRZ digital signal transmission. Based on TowerJazz 0.18 μm SiGe BiCMOS technology
the driver chip consists of 6 individual channels
with a bandwidth of 17.2 GHz
a maximum output swing of 3Vppd and an jitter of 8.9 ps. The chip consumes 646.9 mW from a dual power supply of 2.3/3.6V.
