Abstract We present the world’s first charge-recycling-based low-power technique of complementary metal–oxide–semiconductor (CMOS) magnetic cell manipulation. CMOS manipulation associated with beads is a promissing tool for on-chip biomedical-analysis applications such as drug screening because can integrate control electronics and electro-chemical sensors. However, conventional requires considerable power consumption. In this work, by concatenating multiple unit circuits recycling electric charge among them, consumption reduced factor number concatenated (1/ N ). For verifying effectiveness, test chip was fabricated in 0.6-µm CMOS. The successfully manipulates microbeads achieving 49% reduction (from 51 to 26.2 mW). Even considering additional serial resistance inductors, nearly theoretical effect be confirmed.
