Title:
ELECTRONIC DEVICE AND DIGITAL CHIP
Document Type and Number:
WIPO Patent Application WO/2021/088023
Kind Code:
A1
Abstract:
Disclosed are an electronic device and a digital chip, wherein the digital chip may be a baseband chip. The digital chip can perform DPD correction on a first digital signal to be output. The digital chip can also output a digital cancellation signal, and after a cancellation path converts the digital cancellation signal into an analog cancellation signal, the analog cancellation signal is input into a feedback path. The analog cancellation signal can reduce the signal intensity of a target sampling signal in an analog sampling signal acquired by the feedback path, thereby facilitating the reduction in the hardware requirements for the feedback path.
