In order to achieve the goal, transmitting data through power line is adopted since it saves the cost of extra cable setting. Moreover, to improve the data rate, the signal bandwidth is increased from the 2-28MHz for Home Plug AV specification to the 2-86MHz for Home Plug AV2 specification in this topic. The characteristic of power line is different everywhere in the world. Moreover, the output loading existing in the line driver output is in huge variation due to the channel response. An average value of equivalent resistance for power line is considered in design. For line driver linearity issue, three stage amplifier and feed-forward compensation are used to achieve high loop gain. Damping factor control network and nested Miller compensation technique are used to suppress the open-loop frequency peak and improve stability. As a result, the peaking is suppressed even when the output resistive loading changes. The transmitter amplifier of transmitter analog front end in power line communication is realized in TSMC 90nm CMOS process. Moreover, the supply voltage is 2.5V for I/O usage. Multi-tone power ratio (MTPR) is one of targets in linearity testing. The MTPR measurement result of the output for transmitter is higher than 40 dBc in HomePlug AV and 36dBc for HomePlug AV2. The recovered QAM in HomePlug AV is 256 QAM and 64 QAM for HomePlug AV2 application. Chung-Ping Chen 陳中平 2015 學位論文 ; thesis 51 en_US |

碩士 === 國立臺灣大學 === 電子工程學研究所 === 103 === The high speed communication network in home is indispensable to achieve the vision of digital home. In order to achieve the goal, transmitting data through power line is adopted since it saves the cost of extra cable setting. Moreover, to improve the data rate, the signal bandwidth is increased from the 2-28MHz for Home Plug AV specification to the 2-86MHz for Home Plug AV2 specification in this topic.
The characteristic of power line is different everywhere in the world. Moreover, the output loading existing in the line driver output is in huge variation due to the channel response. An average value of equivalent resistance for power line is considered in design. For line driver linearity issue, three stage amplifier and feed-forward compensation are used to achieve high loop gain. Damping factor control network and nested Miller compensation technique are used to suppress the open-loop frequency peak and improve stability. As a result, the peaking is suppressed even when the output resistive loading changes.
The transmitter amplifier of transmitter analog front end in power line communication is realized in TSMC 90nm CMOS process. Moreover, the supply voltage is 2.5V for I/O usage. Multi-tone power ratio (MTPR) is one of targets in linearity testing. The MTPR measurement result of the output for transmitter is higher than 40 dBc in HomePlug AV and 36dBc for HomePlug AV2. The recovered QAM in HomePlug AV is 256 QAM and 64 QAM for HomePlug AV2 application.
