Abstract
A simple and low-cost circuit for controlling hysteresis of Schmitt trigger is proposed in this paper. The hysteresis of the circuit is digitally tuned by employing binary-weighted resistors in place of feedback resistor. The behavior of proposed circuit has been tested experimentally in hardware. The results obtainedare satisfactory and are also presented.
