A novel voltage controllable Schmitt trigger in nanoelectronic and its innovative applications.

Carbon nanotube FET (CNFET) technology emerges as a promising replacement for MOS technology, offering novel circuit design capabilities with its multi-threshold voltage feature. This paper introduces a novel Schmitt trigger designed based on multi-threshold voltages, allowing direct and precise adjustments of VTL (lower threshold voltage) and VTH (higher threshold voltage) through two external control voltages. The VTL and VTH are nearly equal to these external voltages. These features result in the introduction of two new circuits for nanotechnology in this paper: the hardware implementation of the Hysteresis quantizer and the implementation of the voltage-to-period converter (V2P) circuit. Simulation results using Hspice software and the Stanford 32 nm library show that the proposed circuit exhibits considerable linear control ability, with a 49 % PDP improvement compared to other designs. Additionally, the first hardware implementation of the Hysteresis quantizer in nanoelectronics and the voltage-to-period converter demonstrate proper operation, marking a significant milestone.
