High-speed charge pump circuits using weighted-capacitor and multi-path
Weighted-capacitor와 multi-path를 이용한 고속 승압 회로
Abstract
In this paper two quick boosting charge pump circuits for high-speed EEPROM memory are proposed. In order to improve initial charge transfer efficiency, one uses weighted capacitors where each stage has different clock coupling capacitance, and the other uses a multi-path structure at the first stage. SPICE simulation results show that these charge pumps have improve drising-time characteristics, but their
