Binary hysteresis equal comparator circuits and methods

A method of performing an equal comparison between first and second binary values while providing binary hysteresis, the method comprising:

• reporting, when the first binary value has an initial value not equal to the second binary value, that the first and second binary values are not equal;
• reporting, when the first binary value assumes a value equal to the second binary value, that the first and second binary values are equal;
• and
• continuing to report, when the first binary input value assumes a first new value, that the first and second binary values are equal,
• wherein the first new value differs from the second binary value by a number not exceeding a predetermined constant.

• means for reporting, when the first binary value has an initial value not equal to the second binary value, that the first and second binary values are not equal;
• means for reporting, when the first binary value assumes a value equal to the second binary value, that the first and second binary values are equal;
• and
• means for continuing to report, when the first binary input value assumes a new value, that the first and second binary values are equal,
• wherein the new value differs from the second binary value by a number not exceeding a predetermined constant.

• and
• continuing to report, when the first binary input value decreases to a second new value, that the first and second binary values are equal, wherein the second new value is less than the second binary value by a second number not exceeding a second predetermined constant.
