is enhanced by using proposed adaptive-on/off-time (AOOT) control scheme. The control scheme switches between adaptive-on-time (AOnT) and adaptive-off-time (AOffT) mode according to the target CR. The proposed 3-level buck converter is implemented in a standard 0.25μm CMOS process showing 92.8% maximum efficiency and wide CR. |
