A bionic clock circuit with anti-interference characteristics and its realization method

Abstract

The invention provides an anti-interference bionic clock circuit and an implementation method thereof. The bionic clock circuit comprises a plurality of neuron circuit units used for generating synchronous clock signals, the neuron circuit units can be arranged at physical positions of chips, PCBs (printed circuit board) or the like requiring the clock signals, the neuron circuit units are connected through synapse circuits to form a coupling network, and the synapse circuits are capable of adjusting the neuron circuit units. When interference signals are inputted, owing to the adjustment action of the synapse circuits, the neuron circuit units can still generate the synchronous clock signals identical to those generated in absence of input interference signals, and accordingly clock jittering caused by interference can be reduced; output ends of the neuron circuit units are used for outputting the synchronous clock signals to enable each terminal unit circuit to receive synchronous anti-interference clock signals. The anti-interference bionic clock circuit and the implementation method thereof have the advantages that adaptability of a synchronous digital circuit system to complex electromagnetic interference environments can be improved, effectiveness in resistance to external interferences is achieved, and stable operation of the circuit system can be maintained.

Description

technical field [0001] The invention relates to a clock circuit, in particular to a bionic clock circuit with anti-disturbance characteristics and its realization method. Background technique [0002] In the clock circuit design of a synchronous digital integrated circuit or PCB (Printed Circuit Board, printed circuit board), the clock signal plays a decisive role in the performance and stability of the system. The disorder of the clock signal may lead to errors in a series of system functions such as data calculation and transmission, and even cause system crashes in severe cases. [0003] The skew and jitter of the clock signal are the two most important issues that must be considered in the clock circuit design. The skew of the clock signal refers to the time difference between the arrival of the same clock signal at different terminals. This problem can generally be solved by signal delay. The jitter of a clock signal is the deviation between the actual clock signal a...
