There are many important points for high-speed CMOS integrated circuit, such as switching speed, power dissipation and full-swing of voltage. In this paper, a group of high performance and low-power bootstrapped CMOS drivers are designed in order to reduce power consumption and enhance the speed of switch for driving a large load, where the drivers will reduce the power consumption by using bootstrap manipulate conditional to input statistics. Moreover, the low swing bootstrapped feedback controlled split path (LBFS) is conducted to reduce the dynamic power dissipation and limiting the voltage swing of gate of the output stage. Finally, the charge transfer feedback controlled split path (CRFS) CMOS buffer is used to restitute and pull down the gate voltage for reducing power consumption and line noise. According to the HSPICE simulation results, the proposed drivers of the CMOS driver are reduced by 20%~40 compared to the conventional design.
