Title:
DIGITAL POWER AMPLIFIER AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/217945
Kind Code:
A1
Abstract:
The present application provides a digital power amplifier and a communication system. The digital power amplifier comprises: a decoder and N transistor sets, wherein the decoder comprises an input end and N groups of output ends, the input end of the decoder is connected to a baseband processing unit, the N groups of output ends of the decoder are respectively connected to the N transistor sets, and the N transistor sets operate within at least two different operation voltage ranges. The decoder is used for receiving K quantization levels corresponding to a signal to be amplified from the baseband processing unit, and sending target quantization levels of the K quantization levels within the same operation voltage range to a transistor set, which operates within the operation voltage range. The N transistor sets are used for respectively amplifying the respective received target quantization levels.
