Sub-1V CMOS large capacitive-load driver circuit using direct bootstrap technique for low-voltage CMOS VLSI

A novel sub-1 V CMOS large capacitive-load driver circuit using a direct bootstrap technique for low-voltage CMOS VLSI is reported. For a supply voltage of I V, the CMOS large capacitive-load driver circuit using the direct bootstrap technique shows a 33 times improvement in switching speed in driving a capacitive load of 2 pF compared to the conventional bootstrapped CMOS driver circuit using an indirect bootstrap technique, Even for a supply voltage of 0.8 V. this CMOS large capacitive load driver circuit using the direct bootstrap technique is still advantageous.
