Abstract :
We first analyze the undesired charge transfer occurring in charge pumps; we then 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.
