Title:
ADJUSTMENT CIRCUIT AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/142574
Kind Code:
A1
Abstract:
Disclosed in the present application are an adjustment circuit and an electronic device. The adjustment circuit comprises: a current limiting circuit, which is used for receiving a power source provided by an external power source circuit, and performing a configurable setting on the maximum output current of the power source; an energy storage circuit, which is coupled to the current limiting circuit, and is used for receiving a current-limited power source output by the current limiting circuit, so as to store energy; and a power amplification circuit, which is coupled to the current limiting circuit, the energy storage circuit and an external load, wherein the power amplification circuit is used for receiving an externally input audio signal, acquiring a state value of the load to receive, according to the state value, the power source, the current of which is limited by the current limiting circuit, or to receive, according to the state value, an energy storage power source provided by the energy storage circuit and the power source, the current of which is limited by the current limiting circuit, so as to adjust the audio signal, and outputting the adjusted audio signal to the load. Therefore, the adjustment circuit in the present application can effectively reduce the peak-to-average ratio of the power consumption of a system, such that the peak power consumption of the system is effectively reduced when indexes such as the degree of distortion of an output of a power amplifier are met.
