Title:

COMPENSATING DC LOSS IN USB 2.0 HIGH SPEED APPLICATIONS

Document Type and Number:

WIPO Patent Application WO/2019/140246

Kind Code:

A1

Abstract:

In at least one example, a current source (232) is coupled to a channel input of a switch (234), and an output of the switch (234) is coupled to a positive (140) or a negative data line (150) in a USB 2.0 communication system (200). Also, a first input of a voltage threshold comparator (201) is coupled to the negative data line (150), a second input of the voltage threshold comparator (201) is coupled to the positive data line (140), and an output of the voltage threshold comparator (201) is coupled to a control input of the switch (234).
