The need for high-speed low-power receivers has grown due to the large increase in data rates and Internet-of-Things (IoT) applications. Equalizer-based receivers contain mainly two types of equalizers; Continuous-Time-Linear-Equalizers (CTLE) and non-linear equalizers implemented as Decision-Feedback-Equalizers (DFE). Many solutions have been introduced in the literature to enhance the power consumption of DFEs by using time interleaving or charge-steering. Still, the CTLE power consumption remains considerable a big portion of the overall power of the equalizer-based receivers. The CTLE function cannot be neglected as it equalizes the pre-cursors. This paper presents a low-power charge-steering based receiver that consists of a 1/8-rate charge-steering DFE integrated with a newly proposed Charge-Steering-Linear-Equalizer (CSLE). The proposed CSLE is explained qualitatively and quantitatively. The entire receiver chain consumes 2.9-mW running from a 0.9-V supply and can compensate for 14-dB channel loss at Nyquist-rate when processing 20-Gb/s data.

由于数据速率和物联网（IoT）应用的大幅增长，对高速低功率接收器的需求已经增长。基于均衡器的接收器主要包含两种类型的均衡器：实现为决策反馈均衡器（DFE）的连续时间线性均衡器（CTLE）和非线性均衡器。在文献中已经引入了许多解决方案，以通过使用时间交织或电荷控制来提高DFE的功耗。尽管如此，CTLE功耗仍然占基于均衡器的接收机总功率的很大一部分。CTLE功能不能被忽略，因为它使前光标相等。本文提出了一种基于低功率电荷转向的接收器，该接收器由一个1/8速率电荷转向DFE和一个新提出的电荷转向线性均衡器（CSLE）组成。定性和定量地解释了提出的CSLE。整个接收器链在0.9V电源下消耗2.9mW的功率，并且在处理20Gb / s数据时可以奈奎斯特速率补偿14dB的信道损耗。
