Abstract

The invention relates to a degenerate circuit with a bionic anti-interference characteristic, and a design method thereof. The degenerate circuit comprises an input end, a processing circuit and an output end. The processing circuit is composed of a plurality of node circuit units. The connection relations among the node circuit units in the processing circuit, the connection relation between the processing circuit and the input end and the connection relation between the processing circuit and the output end form a network topology corresponding to the degenerate circuit. The network topology is evolved and generated under the constraint of a multi-target fitness function and a degeneracy characteristic evaluation system according to the object function truth table to be realized of the degenerate circuit and the functions of the node circuit units. At least one pair of partially overlapped sub-circuits with different structures yet the same functions exist in the processing circuit, and these sub-circuits have the effect of function compensation. The circuit internally has a degeneracy characteristic and can improve the reliability and the adaptability of an electronic system in a complex electromagnetic environment.

Description

technical field [0001] The invention relates to a circuit based on the bionic concept and characterized by anti-disturbance and fault-tolerant operation, in particular to a degenerate circuit with bionic anti-disturbance characteristics and a design method thereof. Background technique [0002] Electromagnetic interference is the process in which unwanted voltages and currents affect the performance of equipment. These voltages and currents can have undesired effects on victim equipment through conduction or electromagnetic field radiation. There must be three factors at the same time to form electromagnetic interference: (1) the source of electromagnetic interference, that is, the "transmitter"; (2) the "receiver" sensitive to this type of interference energy; (3) the coupling of energy from the interference source to the On the receiver, the medium that significantly deteriorates the performance of the system, or the coupling channel. [0003] By "transmitter" is meant a ...
