Abstract :
The proposed circuit is a dual pumping chain Dickson-type charge pump using both active and passive charge transfer switches and adaptive control of the clock amplitude in order to improve the power efficiency. The circuit is sourcing up to 500μA at 5V-6.5V above the battery voltage as part of a high side driver [5] and uses a battery related “floating ground” regulator to deliver the supply voltage for the charge pump core.
