Abstract

This paper presents a low voltage adjustable CMOS Schmitt trigger using dynamic threshold MOS (DTMOS). Cross-coupled inverter with body control is employed to speed up the switching process, and control the intensity of the feedback. The proposed Schmitt trigger has been designed using 0.18 m 0.4 V CMOS technology and analyzed using PSPICE with BSIM3V3 device models. The simulation results show rail-to-rail operation and independently adjustable switching voltages for both low-to-high (VT(LH)) and high-to-low (V T(HL)) as high as 15 % of the supply voltage. The power dissipation is 0.13 W. © 2011 IEEE.
