ABSTRACT:
To remove ringing from pulse. A buffer amplifier (30) is inserted in series into a path through which a signal is transmitted. Ringing caused in the output of the buffer amplifier (30) is detected by an L side comparator (31) and an H side comparator (32). When ringing is detected, a current is supplied into the input of the buffer amplifier (30) through an L side current supply circuit (33) or an H side current supply circuit (34). By supplying a current from the L side and H side current supply circuits (33, 34), the overshooting portion due to ringing can be suppressed.
