摘　　要：作为光接收机前端的关键部分,限幅放大器要求具有高增益、足够带宽以及较宽的输入动态范围。本文在0.18滋m1P6MCMOS工艺上设计了一种用于10Gb/s传输速率的限幅放大器。该限幅放大器的增益S21可达31dB,-3dB带宽为11.3GHz,在10GHz范围内S11、S22均小于-10dB。对于从10mVpp至1.5Vpp的较宽的输入动态范围,均可保持稳定的输出眼图。利用CMOS工艺中、多层金属互连线的顶层金属设计的共面带状线,可将放大器的工作频带扩展至10Ghz以上。As the key component of optical receiver, design of a high-speed limiting amplifier with high gain, broadband, and a wide dynamic input range is required.A limiting amplifier implemented in 0.18μm 1P6M CMOS technology for low-cost 10Gb/s application is described. The total gain is 31dB, -3dB bandwidth of S21 reaches 11.3GHz. Parameters S11 and S22 are better than -10dB in the 10GHz frequency range.A good output eye diagram can be available in a wide dynamic input range from 10mVpp to 1.5Vpp. Coplanar stripline in the top metal layers extends the bandwidth of the amplifier beyond 10GHz.
