Abstract

The invention discloses a circuit for taking power from a transmission line, comprising: a first inductance and a second inductance connected between a first differential output line and a second differential output line, wherein one end of the first inductance connected to the first differential transmission line, one end of the second inductor is connected to the second differential transmission line, and the other end of the first inductor is connected to the other end of the second inductor; and a boost circuit, the The input end of the boost circuit is connected to the connection node between the other end of the first inductor and the other end of the second inductor.

Description

technical field [0001] The invention relates to the field of electronic technology. Specifically, the present invention relates to a circuit for taking power from a high-speed transmission line. Background technique [0002] With the increasingly widespread application of optical communication, many occasions where cables are used as communication media are replaced by optical cables. Optical cables have incomparable advantages over cables, but they also have obvious disadvantages. Optical cables cannot supply power. In the past, the power supply was not needed in some occasions when the cable was transmitted, and the signal was directly transmitted from the cable. After being changed to an optical cable, it needs to undergo photoelectric conversion. In those occasions that do not provide a power supply interface, it is necessary to take power from the signal line. [0003] Therefore, there is a need in the art for a circuit capable of taking power from a high-speed transmi...
