Abstract
A hysteresis receiver containing two inverters and a logic controller. The inverters are implemented with threshold voltages equaling Vil and Vih, which together define the hysteresis window. The inverters receive the input signal and generate a respective inverted value. The logic controller propagates as output one of the two inverted values if the two inverted values are equal, and a prior value (corresponding to a previous sample) if the two inverted values are not equal. A receiver circuit with a hysteresis window defined by Vil and Vih, is obtained as a result.
