A comparator without hysteresis has only one switching level. Comparators – Part 2 - Hysteresis Definition Hysteresis is the dependence of a circuit not only on its present state but also on its past state. A comparator without hysteresis has only one switching level. A comparator with hysteresis has two switching levels. When the input signal goes upwards, the comparator uses the upper switching level. When the input signal goes downwards, the comparator uses the lower switching level. Operational Amplifiers

A comparator without hysteresis has only one switching level. Comparators – Part 2 - Hysteresis Description A comparator without hysteresis has only one switching level. Operational Amplifiers

A comparator with hysteresis has two switching levels. Comparators – Part 2 - Hysteresis Description A comparator with hysteresis has two switching levels. Operational Amplifiers

Comparators – Part 2 - Hysteresis Description If we want to convert a clean sinusoidal input signal to a rectangular shape, a comparator without hysteresis is OK. The output voltage is clean. Operational Amplifiers

Comparators – Part 2 - Hysteresis Description But if the input signal is distorted with noise, the output rectangular signal of a comparator without hysteresis is unusable. Operational Amplifiers

Comparators – Part 2 - Hysteresis Description If we use a comparator with hysteresis, the output rectangular signal is clean. Operational Amplifiers

Comparators – Part 2 - Hysteresis Description The resistors R1 and R2 introduce a small amount of positive feedback. Due to this feedback the comparator switches at about +1V when the input signal is going up, and at about -1V when the input is going down. Operational Amplifiers

Non-inverting  Inverting Comparators – Part 2 - Hysteresis Task In the above explanations we used a non-inverting comparator. Try to draw an inverting comparator with a similar hysteresis. Non-inverting  Inverting Operational Amplifiers

Just swap the input terminal and the ground. Comparators – Part 2 - Hysteresis Solution It is simple, isn‘t it? Just swap the input terminal and the ground. Operational Amplifiers
