Abstract: Abstract Schmitt trigger is a comparator circuit with hysteresis, implemented by applying positive feedback to a noninverting input. Recently, it has been verified that noise under certain condition can help nonlinear circuit to realize reliable logical stochastic resonance (LSR). In this letter, we demonstrate that, without any modifications, Schmitt trigger can operate flexibly both as logic operation and latch operation in an optimal noise range. In traditional Schmitt trigger, the hysteresis is designed for resisting noise. In the new design, the hysteresis tends to enhance the LSR effect in Schmitt trigger with the help of noise and helps the system to perform better at higher noise levels. Thus, our results extend the application scope and generality of the traditional Schmitt trigger. Highlights • The Schmitt trigger is a two-state system with two thresholds action called hysteresis. • The purpose of the hysteresis in Schmitt trigger is to resist or clean noise. • Schmitt trigger can exploit logical stochastic resonance to operate flexibly both Logic operation and Latch operation. • The hysteresis tends to enhance reliable logic and Latch operation with the help of noise.
