Abstract:
The present technology relates to an amplifier, an audio signal output method, and an electronic device that can inhibit unintended sound output in a class D amplifier that changes a peak value of a PWM signal. The amplifier includes: a positive-side amplitude generating circuit configured to generate positive-side amplitude of an output PWM signal that is a PWM signal to be output outside an apparatus; a negative-side amplitude generating circuit configured to generate negative-side amplitude of the output PWM signal; and a feedback circuit configured to feed back a difference between the amplitude generated by the positive-side amplitude generating circuit and the amplitude generated by the negative-side amplitude generating circuit to the positive-side amplitude generating circuit and the negative-side amplitude generating circuit. The present technology is applicable, for example, to an amplifier or the like of an electronic device such as an audio player.

Claim (Index 8):
The electronic device according to  claim 7 , further comprising:\n an acquisition unit configured to acquire audio data; a PWM signal generating unit configured to generate a PWM signal corresponding to the acquired audio data; and a speaker configured to output a sound on the basis of a signal obtained by the amplifier performing power amplification on the PWM signal generated by the PWM signal generating unit.
