Abstract

The application provides a digital power amplifier for reducing a peak-to-average ratio of a signal, a related method and device. The digital power amplifier provided by the application can select different signal amplification modes based on the power of a digital signal. Specifically, a CMOS complementary metal oxide semiconductor amplification module is used to amplify and process a low-power digital signal, which helps to improve the output power of the low-power input digital signal, reduce the peak-to-average ratio of the output signal, and thus improve the communication quality of a terminal device.
