An input buffer having a comparator that receives an input signal, a reference signal and a positive feedback. The comparator compares the input signal relative to the reference signal and generates an output signal transitioning between a first logic state and a second logic state responsive to the magnitude of the input signal transitioning through the magnitude of the reference signal. The comparator intensifies the output signal in response to the positive feedback from the output of the comparator while the output signal transitions from the first logic state to the second logic state.
