ABSTRACT
This paper presents different low voltage adjustable CMOS Schmitt trigger using DCG-FGT transistor. Simple circuits are introduced to provide flexibility to program the hysteretic threshold in this paper. The hysteresis can be controlled accurately at a large voltage range. The proposed Schmitt trigger have been designed using 90nm 1.2V CMOS technology and simulated using Eldo with PSP device models. The simulation results show rail-to-rail operation and adjustable switching voltages VTH- (low switching voltage) and VTH+(high switching voltage).
