A New Charge Pump Switch Parallel to Series Connection

Abstract

This paper proposed increase 2VIN+VCLK voltage series charge pump. Recently, trend of low power circuit designs a lower input voltage. But several circuit require high voltage. In this case, charge pump solves a problem with small area and cheap cost. Many Conventional charge pumps are connected parallel each capacitor. So many capacitors are required for high voltage. However proposed charge pump can supply high voltage easily and design less capacitors. Proposed circuit are comprised 2-stages with 5 capacitors. To compare with conventional charge pumps, proposed circuit design same component units.
