摘要: This paper presents an energy efficient bootstrapped CMOS driver to enhance switching speed for driving large RC load for ultra low-voltage CMOS VLSI. The proposed bootstrapped driver eliminates the leakage paths in the conventional bootstrapped driver to achieve more positive and negative boosted voltage levels and to allow the boosted nodes to maintain the boosted levels, thus improving boosting efficiency and enhancing the switching speed. Performance evaluation based on UMC 65nm low power technology (Vtn approximate to Vtp approximate to 0.5v) indicates that the proposed driver provides rising-delay improvement of 24%-56% and falling-delay improvement of 9%-30% at V-dd = 0.3 V for 1 to 10 segments of large distributed RC loading, as compared with the conventional bootstrapped driver consuming the same power. Although designed and optimized for ultra low-voltage operation, the proposed bootstrapped driver is shown to be advantageous at high supply voltage as well.
