ABSTRACT:
A circuit includes a middle-voltage-detection circuit which detects a substantially middle voltage between a HIGH level and a LOW level of a signal voltage, and supplies the substantially middle voltage as a reference voltage. The circuit further includes a differential amplifier which receives the signal voltage and the reference voltage.
