Claims
- 1. A method for generating hysteresis in a comparator comprising the steps of:
- enabling a current path which is in parallel to a transistor of a differential pair when an output of the comparator is at a high voltage, wherein the transistor receives a differential input signal; and
- not enabling the current path when the output of the comparator is at a low voltage.
- 2. The method of claim 1 wherein the step of enabling the current path is performed using a MOSFET transistor.
- 3. The method of claim 2 wherein the MOSFET transistor is a N-channel transistor.
- 4. A method for generating hysteresis in a comparator comprising the steps of:
- enabling a current path which is in parallel to a transistor of a differential pair when an output of the comparator is at a high voltage, wherein the transistor receives a differential input signal.
- 5. The method of claim 4, comprising the further step of:
- not enabling the current path when the output of the comparator is at a low voltage.
