Title:
LINE DRIVE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/169929
Kind Code:
A1
Abstract:
Provided is a line drive apparatus. The apparatus comprises: a signal output module for outputting a first signal to a first power supply module, outputting a second signal to a second power supply module, and outputting a third signal to a line drive module; the first power supply module for generating a corresponding first voltage according to an amplitude of the first signal at each moment, and outputting the first voltage to the line drive module, wherein the difference between an amplitude of the first voltage at this moment and an amplitude of the first signal at this moment is within a set range; the second power supply module for determining whether an absolute value of an amplitude of the second signal is greater than or equal to a set threshold value, and if so, generating a second voltage according to the amplitude of the second signal, and outputting the second voltage to the line drive module, otherwise, not outputting a signal, wherein an amplitude of the second voltage is greater than the amplitude of the second signal; and the line drive module for performing power amplification on the third signal based on the first voltage and the second voltage.
