A 1.5-V full-swing bootstrapped CMOS large capacitive-load driver circuit suitable for low-voltage CMOS VLSI

This paper reports a 1.5-V full-swing bootstrapped CMOS large capacitive-load driver circuit using two bootstrap capacitors to enhance the switching speed for low-voltage CMOS VLSI. For a supply voltage of 1.5 V, the full-swing bootstrapped CMOS driver circuit shows a 2.2 times improvement in switching speed in driving a capacitive load of 10 pF as compared to the conventional CMOS driver circuit. Even for a supply voltage of 1 V, this full-swing bootstrapped CMOS large capacitive-load driver circuit is still advantageous.
