Comparison Between Comparator and Schmitt Trigger
PARAMETERS | COMPARATOR | SCHMITT TRIGGER |
---|---|---|
1. USE OF FEEDBACK | No feedback op-amp used in open loop configuration. | Uses positive feedback. |
2. TRIGGER LEVELS | At 0V or at V ref . | |
3. OUTPUT VOLTAGE | +V sat or -V sat | +V sat or -V sat. |
4. HYSTERESIS | 0V |
Zero Crossing Detector
A voltage comparator circuit whose output changes concerning the input signal which is crossing the zero of the reference voltage level that’s why it is called a Zero Crossing Detector. These circuits are commonly known as switching circuits the output of these circuits lies between positive and negative saturation voltage levels. The most commonly used circuits are the Schmitt trigger, Astable, and Monostable Multivibrators.
