摘要： A noise cancelling circuit includes a delay circuit (19) for delaying an input signal which is supplied to an input terminal (18), and a signal processing circuit (Q1 to Q6, 23) responsive to the input signal and an output signal from the delay circuit (19), to generate an output signal corresponding to the input signal. The signal processing circuit has a first switching circuit, which includes first and second switching elements (Q1 and Q3) connected in series between a first power supply terminal (Vcc) and an output (20), and a second switching circuit, which includes third and fourth switching elements (Q2 and Q4) connected in series between a second power supply terminal and the output (20), wherein the first and third switching elements (Q1 and Q2) are responsive to the aforementioned input signal, by which they are set in mutually opposite conduction states, and the second and fourth switching elements (Q3 and Q4) are responsive to the output signal of the delay circuit (19), by which they too are set in mutually opposite conduction states.
