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 2):
The amplifier according to  claim 1 , further comprising an output amplitude setting circuit configured to set the amplitude of the output PWM signal,\n wherein the output PWM signal of the amplitude that is set by the output amplitude setting circuit is supplied to the positive-side amplitude generating circuit and the negative-side amplitude generating circuit.
