In this paper, a set of low-voltage bootstrapped CMOS drivers are presented to reduce power consumption and improve switching speed for driving a large capacitive load. The proposed drivers can reduce the power consumption by making bootstrap operations conditional to input statistics. They also improve switching speed by providing larger bootstrap voltages for the same amount of integrated bootstrap capacitance as compared with conventional bootstrapped drivers. The proposed drivers were designed using 0.18- CMOS technology. The comparison results indicate that the proposed drivers achieve power savings up to 97% with 13%-22% improvements on switching speed as compared with the conventional design.
