Lots of information regarding circuit, speed sensors, hall sensor, rotational speed sensor, and speed sensor are explained inside the paper. The following are taken from the paper:

( ) Vhyst = I HI MIN − I LOMAX ⋅ RS VrefTYP = ( ) ΔVth = (5) 2 Taking into consideration the worst case supply current limits of the speed sensor, which should be used in the implemented application circuit, the equation will be: (3) Considering the other components tolerances of the interface circuit, like 1% precision for the shunt resistor and the threshold voltage divider resistors, 1% accuracy of the supply voltage (VDC = 5V), using equations (4) the resulted worst case maximum hysteresis will be: VhystWC < 336,5mV.

Even more, this paper presents discussion about the interface circuit, the speed sensor, measurement, and the voltage comparator.
