Abstract

This paper presents the single supply power line communication(PLC) SoC ASIC with built-in analog frond-end circuit. To achieve the low power consumption along with low chip cost, this PLC SoC ASIC employs fully CMOS analog front-end(AFE) and several built-in Regulators(LDOs) powering for Core logic, ADC, DAC and IP Pad driver. The AFE includes RX of pre-amplifier, Programmable gain amplifier and 10 bit ADC and TX of 10bit Digital Analog Converter and Line driver. This PLC Soc was implemented with 0.18um 1 Poly 5 Metal CMOS process. The single power supply of 3.3V is required for the internal LDOs. The total power consumption is below 30mA at standby and 300mA at active which meets the eco-design requirement. The chips size is $3.686\;{\times}\;2.633\;mm^2$.

본 논문은 전력선 통신용(PLC) SoC ASIC으로 내장된 Analog Front-end(AFE)를 바탕으로 낮은 소비 전력과 저 가격을 달성할 수 있었으며, CMOS공정으로 구현된 AFE와, 1.8V동작의 Core Logic구동용 LDO, ADC, DAC와 IO pad를 구동하기 위한 LDO로 구성되어 있다. AFE는 Pre-amplifier, Programmable gain Amplifier와 10bit ADC의 수신 단으로 구성되며, 송신 단은 10bit differential DAC, Line Driver로 구성되어 있다. 본 ASIC은 0.18 um 1 Poly 5 Metal CMOS로 구현 되었으며, 동작전압은 3.3 V단일 전원만 사용하였고, 이때 소모 전력은 대기 시에 30mA이며, 동작 시 전력은 300mA으로 에코 디자인 요구를 만족하게 하였다. 본 칩의 Chip size는 $3.686\;{\times}\;2.633\;mm^2$ 이다.
