摘要：
随着先进工艺和技术的不断进步，要想保证数据在高速传输中的正确性，均衡器需要有更高的补偿和更低的功耗，才能实现高效通信。基于12 nm 互补金属氧化物半导体工艺，设计了一种高增益、低功耗的自适应连续时间线性均衡器（continuous time linear equalizer, CTLE），该均衡器采用2级级联结构来补偿信道衰减，并提高接收信号的质量。此外，自适应模块通过采用符号-符号最小均方误差(sign-sign least mean square, SS-LMS)算法，使抽头系数加快了收敛速度。仿真结果表明，当传输速率为16 Gbit/s时，均衡器可以补偿-15.53 dB的半波特率通道衰减，均衡器系数在16×104个单元间隔数据内收敛，并且收敛之后接收误码率低于10-12。

Abstract：
With the continuous advancement of advanced processes and technologies, in order to ensure the accuracy of data during high-speed transmission, equalizers need to provide higher compensation and lower power consumption to achieve efficient communication. A high-gain and low-power adaptive CTLE(continuous time linear equalizer) was designed on the basis of the 12 nm CMOS(complementary metal-oxide-semiconductor) process, which adopted a two-stage cascade structure to compensate for channel attenuation and improve the quality of the received signal. In addition, the adaptive module used the SS-LMS(sign-sign least mean square) algorithm to accelerate the convergence speed of the tap coefficients. Simulation results show that when the transmission rate is 16 Gbit/s, the equalizer can compensate for a half-bit rate channel attenuation of -15.53 dB, and the equalizer coefficients converge within 16×104 unit interval data. Moreover, after convergence, the received error rate is lower than 10-12.
