ABSTRACT:
In an input buffer circuit arrangement, a comparator compares a filtered input signal applied to one input with each of a first and a second reference value preset at the other input by a first setting circuit to produce a comparison output signal. According to the comparison output signal, a second setting circuit provides a third and a fourth reference value to one input of the comparator to obtain a noise-resistive characteristic.
