Abstract

This paper presents a new circuit technique to alleviate the uncontrollable floating-body-induced hysteretic component present in the transfer characteristics of voltage-mode CMOS Schmitt trigger circuits in a partially depleted silicon-on-insulator technology. This technique integrates a successive switching threshold shift mechanism with the systematic body contact scheme, resulting in improved noise immunity and well-defined hysteresis behavior for the Schmitt trigger circuit that is suitable for use as a low-noise receiver, level shifter, waveform-reshaping circuit, and delay element in very large-scale integrated applications.
