摘要
Here, first, we analyze the undesired charge transfer occurring in charge pumps; afterwards we present a circuit which is less susceptible to this issue, resulting in significant improvements of the light load efficiency in charge pumps which must have a sufficiently high maximum current capability. SPICE simulations confirm the theoretical results.
