Abstract
In this paper, the regulated dual phase charge pump with compact size is presented. This charge pump uses the dual phase technique to reduce the output ripple and proposes a new power stage to define the stability of the overall system. This charge pump provides output voltage 5V and maximum load current 50 Am with the constant frequency regulation. This design is based on TSMC 035 mum 3.3V/5V CMOS technology.
