摘　　要：文章介绍了一种用IBM公司0.5μmSiGeBiCMOSHBT工艺设计的12Gbit/s用于光纤传输系统的限幅放大器。整个系统包括一个输入缓冲级、三个放大单元、一个用于驱动50传输线的输出缓冲级和一个失调电压补偿回路。采用3.3V单电源供电,功耗只有150mW,小信号增益大于35dB,在40dB的输入动态范围内输出电压幅值可以保持800mVpp恒定。A 12Gbit/s limiting amplifer for fiber-optic transmission system is realized in a IBM 0.5μm SiGe BiCMOS HBT technology. The whole circuit consists of an input buffer, three amplifer cells, an output buffer for driving 50transmission lines and a pair of feedback networks for offset cancellation. At a positive single supply voltage of 3.3V, the power dissipation is about 150mW, the small-signal gain is higher than 35dB and the input dynamic range is about 40 dB with a constant output voltage swing of 800mVpp.
