چکیده :

This paper present a buffer Schmitt trigger (ST) with six-transistors and adjustable hysteresis width via controlling Upper Threshold Point (UTP) in Carbon Nano-Tube Field Effect Transistor (CNTFET) 32nm technology node. The adjust-voltage for proper operation of this circuit is 0.44 volt to 0.68 volt which is less than the supply voltage. Due to the wide hysteresis width of this circuit, it has a good ability to reject large noise and fluctuate at its input signal. The proposed circuit is simulated in the H-SPICE platform using the 32nm Stanford model. In this ST circuit the delay and power delay product (PDP), 75.80% and 76.10% have been reduced respectively in comparison to the conventional one. Because of CNTFET technology usage for this circuit, PDP is almost independent of temperature variation. The static power dissipation and average dynamic power of this design at 500MHz frequency 48pW and 1.28µW are measured respectively.
