VOLTAGE AMPLITUDE DETECTION CIRCUIT, INFORMATION STORAGE DEVICE, COMMUNICATION DEVICE, AND VOLTAGE AMPLITUDE DETECTION METHOD

摘要

There is provided a voltage amplitude detection circuit including a first comparison unit configured to compare a voltage amplitude of an input signal with a predetermined voltage and output a comparison result; a first comparison result holding unit configured to hold the comparison result output from the first comparison unit in predetermined periods of a driving clock, and output the held comparison result; and a first comparison result evaluation unit configured to evaluate the comparison result output from the first comparison result holding unit in the predetermined periods of the driving clock and output an evaluation result.
