Design and Implementation of Schmitt Trigger using Operational Amplifier
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 1
Abstract
A Schmitt trigger is an electronic circuit, a Comparator that is used to detect whether a voltage has crossed over a given reference level. It has two stable states and is very useful as signal conditioning device. Whe n an input waveform in the form of sinusoidal waveform, triangular waveform, or any other periodic waveform is given, the Schmitt trigger will produce a Rectangular or square output waveform that has sharp leading and trailing edges. Such fast rise and fall times are desirable for all digital circuits. The state of the art presented in the paper is the design and implementation of Schmitt trigger using operational amplifier µA-741, generating a Rectangular waveform. Furthermore, the Schmitt trigger exhibiting hysteresis is also presented in the paper. Due to the phenomenon of hysteresis, the output transition from HIGH to LOW and LOW to HIGH will take place at various thresholds.
