Summary This letter introduces a novel scheme to improve charge transfer switches in linear charge pumps. The proposed approach relies on the reduction of the threshold voltage of the transistor implementing each charge transfer switch by forcing a current into its bulk junction. Simulation results using a 130‐nm standard complementary metal‐oxide semiconductor (CMOS) technology confirm the effectiveness of the proposed method.
