Coupling system of oscillator

Abstract

The invention relates to an oscillator coupling system, comprising a plurality of oscillating elements and a plurality of delay elements, the delay elements are connected between at least two oscillating elements and there is a specific phase or time delay relationship between the plurality of delay elements, Coupling the phase or frequency noise suppression correlation characteristics of the at least two oscillating elements through the delay element reduces the auto-correlation of noise in the operation of the circuit system, so as to improve the suppression effect of phase or frequency noise, and avoid the use of space-consuming solid-state loops device or isolator or resonant cavity to reduce signal distortion and increase system stability.

Description

technical field [0001] The present invention relates to a noise reduction technology, in particular to an oscillator coupling system applied to provide phase or frequency noise suppression in high frequency / low frequency environments. Background technique [0002] In communication circuits and electronic systems, noises generated by signal sources or oscillation generating components will limit the overall efficiency of the system. Among them, there are many reasons for noise interference, such as lightning strikes, switching of peripheral load equipment, generators, Radio communication, poor wire contact, poor switch engagement, improper grounding and radio wave interference, etc. If the phenomenon of noise generation is not eliminated, it will easily lead to random errors in data file access or executable files on storage devices, and it will easily cause abnormal operations of calculators and controllers or interfere with communication systems on electronic products.

Problems solved by technology

[0008] However, due to the advancement of science and technology, the frequency of satellite communication, satellite network, satellite positioning, and wireless network is getting higher and higher, which has reached tens of MHz to tens of GHz. The aforementioned technology of coupling at least two oscillators If the influence of noise cannot be reduced more effectively, the signal-to-noise ratio of the entire communication system will be limited, which will affect the minimum detectable signal power of the system, so that the effective transmission and reception distance of the signal is limited, and there is a bandwidth insufficient problems arise

[0009] Therefore, how to effectively solve the problems existing in the above technologies, and develop a system that can meet the requirements of high-frequency circuits and have better phase or frequency noise suppression effects, so as to increase the system operating bandwidth, improve operating efficiency and avoid phase or frequency noise Affecting the output effect is an urgent problem to be solved in related fields
