Power Efficiency Optimization of Fully Integrated Dickson Charge Pumps
نویسنده
چکیده
This paper describes how the power efficiency of fully integrated Dickson charge pumps in advanced smart power technologies can be improved considerably by implementing charge recycling techniques and the replacement of normal PN junction diodes by pulse-driven active diodes. These 2 methods are first analyzed and compared on a purely theoretical basis and are verified with experimental data afterwards. Measurements reveal that the combination of the 2 methods can boost the power efficiency by a factor of 2 compared to traditional Dickson charge pump designs. Key-Words: Dickson charge pump, high-voltage generator, smart power technology, charge recycling, power efficiency optimization, active diode, display driver.
