Abstract: Disclosed is an integrated circuit, comprising a first MOS transistor, wherein a first effective gate (G1) and a second effective gate (G2) are disposed in the first MOS transistor, and a first redundant gate (DG1) is disposed between the first effective gate (G1) and the second effective gate (G2); the first effective gate (G1), the second effective gate (G2), and the first redundant gate (DG1) cover a plurality of fins arranged in parallel; the first effective gate (G1) and the second effective gate (G2) are connected to a gate terminal of the first MOS transistor; the fins at two sides of the first effective gate (G1) and the fins at two sides of the second effective gate (G2) are respectively connected to a source terminal (S1) and a drain terminal (D1) of the first MOS transistor; and the first redundant gate (DG1) is connected to a redundant potential or is suspended. By means of the structure of a redundant gate (DG1/DG2) disposed between two effective gates, the current density of a MOS transistor per unit can be reduced, and the heat dissipation performance can be further improved.

Abstract: The present invention belongs to the technical field of underwater communications. Provided is a new high-robustness underwater optical communication system, wherein the system is divided into a sending module and a receiving module. According to the new high-robustness underwater optical communication system, high-robustness underwater optical communication under the strong interference of sunlight and an artificial light source is realized. The system uses a brand-new physical method which is irrelevant to frequency, and which can be used in combination with an existing modes, such as MIMO and CDMA, so as to obtain a better communication effect. Circularly polarized light is used for signal transmission, such that the problem of underwater channel dislocation caused by platform rotation is prevented, and signal characteristics are not easily lost due to the good polarization maintaining performance of a marine environment.
