A first control potential setting means ( 1 ) generates a first control potential (N 2 ) which reverses the magnitude relationship with a second control potential (N 3 ) when an input signal (IN) reaches the vicinity of a logical threshold value. A second control potential setting means ( 2 ) generates the second control potential (N 3 ) which changes in the same direction as the input signal (IN), in accordance with a change in input signal (IN). An output means ( 3 ) includes transistors (Q 5 , Q 6 ), and generates an output signal (OUT) having a predetermined potential on the basis of the first control potential (N 2 ), the second control potential (N 3 ), and a reset signal (RSET). A reset means ( 4 ) turns off the transistor (Q 6 ) while a waveform shaping circuit is in operation.
