ABSTRACT:
In a current sense amplifier for detecting and amplifying the difference between the currents flowing on a pair of signal lines, an active device is provided that works to limit the amplitude of an output node of the current sense amplifier. Further, a differential amplifier for amplifying the amplitude-limited output of the current sense amplifier is provided on the output side of the current sense amplifier.
