Abstract
Systems and methods are disclosed for low-swing Schmitt triggers. For example, an apparatus includes a Schmitt trigger including an input node, an output node, and a feedback node that is configured to bear a feedback voltage level that is a sum of an input voltage level at the input node and an attenuated voltage level of the output node; a current source connected to the output node; a voltage sensor connected to the feedback node and configured to cause the current source to pull up an output voltage level at the output node responsive to the feedback voltage level crossing a threshold.
