A 90nm CMOS Dual-Channel Powerline Communication AFE for Homeplug AV with a Gb Extension

📋 论文概要

该论文介绍了一款采用90nm CMOS工艺的双通道电力线通信模拟前端(AFE)，用于支持千兆扩展的Homeplug AV标准。它集成了增益可编程放大器(PGA)和10位流水线ADC，解决了电力线通信中的宽带信号接收问题。

💡 主要创新点

• 提出了一种双通道AFE架构，支持Homeplug AV的千兆扩展，提高了数据速率。
• 实现了-18dB至51dB宽增益范围的PGA，步进3dB，最大增益下输入参考噪声低至30μVrms。
• 采用10位100MHz流水线ADC在1.2V稳压电源下工作，提升了信号数字化精度。

At maximum gain, the measured in-band input-referred noise is 30µVrms. The PGA output is then digitized by a 10b pipelined ADC [3], running at 100MHz on a regulated 1.2V supply. Figure 25.7.2 shows the data rates achieved during reception of a training sequence versus gain settings. As expected, the throughput decreases at high gains, but a theoretical maximum data rate of 180Mb/s with a BER=1e-3 (without FEC) is achieved. 1 2 Powerline communications is currently emerging as a strong candidate for in-home multi-media content distribution. Recently, products have become available that support 200Mb/s rates over
