Abstract
According to an embodiment, a power supply noise cancelling circuit includes a generator, a first multiplier, a subtractor and a digital-to-analog converter. The generator generates a sine wave signal. The first multiplier multiplies a digital input signal by a digital signal based on the sine wave signal to generate a first digital product signal. The subtractor subtracts a digital signal based on the first digital product signal from the digital input signal to generate a digital difference signal. The digital-to-analog converter performs a digital-to-analog conversion on the digital difference signal to obtain an analog output signal.
