A Wireline Termination Embedded Energy Harvesting System With 300-μW Extracted

An energy harvesting system with a three-phase rotating and 5×time-interleaving switched capacitor (SC) is proposed to be embedded in a wireline I/O interface. By a 50-Ω (Z
₀
) mimicking at the termination to harvest the energy from the wireline received signal, the harvesting system can extract 300-μW net power. The proposed energy harvester is fabricated in a 40-nm CMOS technology.
