In this paper, the authors present a single supply PLC SoC ASIC with a built-in analog front-end circuit. To achieve the low power consumption along with low cost, this PLC SoC employs fully CMOS Analog Front End (AFE) and several Low DropOut regulator (LDO) to provide the internal power for logic core, DAC and input/output pad driver. The receiver part of the AFE consists of pre-amplifier, gain amplifier and 1-bit comparator. The transmitter part of the AFE consists of 10-bit digital analog converter and line driver.
