| titleOfInvention | An audio adaptive boost circuit, BOOST chip and audio equipment |
| abstract | The invention is applicable to the field of integrated circuits, and provides an audio adaptive boost circuit, a BOOST chip and audio equipment. The circuit includes: an input voltage detection unit, which detects and determines the voltage level of a power supply, and generates a power supply voltage level signal correspondingly. The audio signal detection unit detects the voltage amplitude of the audio input signal, and generates an audio amplitude level signal according to the voltage amplitude of the audio signal; the voltage control unit selects the corresponding voltage gear according to the power supply voltage gear signal, and according to the audio amplitude The level signal selects the boosting control signal of the corresponding voltage level in the selected voltage gear; the boosting unit performs boosting according to the boosting control signal. The invention automatically detects the power of the power supply, selects the boosting range correspondingly, increases the boosting range, reduces the loss, and further adjusts the boosting output according to the audio frequency, and keeps the boosting gain and the audio gain matching, reducing the loss to the minimum . |
