ABSTRACT:
A first control potential setting means (1) generates a first control potential (N2) which reverses the magnitude relationship with a second control potential (N3) 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 (N3) 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 (Q5, Q6), and generates an output signal (OUT) having a predetermined potential on the basis of the first control potential (N2), the second control potential (N3), and a reset signal (RSET). A reset means (4) turns off the transistor (Q6) while a waveform shaping circuit is in operation.
