Abstract

This paper proposes a design of direct bootstrapped CMOS Schmitt trigger circuit by using direct bootstrapped technique, bootstrapped capacitor boots for the higher voltage than power supply in order to drive the output section for improving the switching speed in driving a capacitive load. All simulation results have been carried out based on PSpice program simulator by using 0.35 μm CMOS technology with level 3. The propagation delay time of the proposed circuit becomes less at 2.186 ns, low power dissipation and gives a full swing output voltage at 1 voltage supply and also operates at 100 MHz, it is higher 10 times as a previous result when compared with the conventional CMOS Schmitt trigger circuit and reshaping CMOS Schmitt trigger circuit. © 2004 IEEE.
