  • Patent number: 11323129
    Abstract: The present disclosure provides a circuit for generating a multi-phase clock having random disturbance added thereto. The circuit for generating a clock includes a main clock module, a random signal generation module and a buffer matrix switch module. The main clock module generates N multi-phase clock signals; and the buffer matrix switch module randomly switches, under the control of a random control signal output by the random signal generation module, transmission paths of the input N multi-phase clock signals, and outputs N multi-phase clock signals with random disturbance. In the present disclosure, the clock phase error is whitened by adding random disturbance. Only with a small loss of signal-to-noise ratio, the influence of a multi-phase clock phase error on the performance of a high-precision TI ADC can be eliminated in real time, and the influence of the fluctuation of a clock phase error can be tracked and eliminated.

  • Publication number: 20170219333
    Abstract: The present invention provides the Fabry-Perot (F-P) sensor compromising housing, measuring probe, longitudinal sling block, and displacement converting device. The optic fiber passes through upside sealing ring and extends into upside through hole with the optic fiber end surface disposed at the bottom; the upside of longitudinal sliding block is disposed with reflecting surface, thus a Fabry-Perot cavity is formed between part of the fiber end surface at the bottom of the fiber and the reflecting surface on the upside of longitudinal sliding block. The displacement converting device will convert the lateral slides of the measuring probe into the slides of the longitudinal sliding block, which thus changes the distance from the reflecting surface to the fiber end surface and changes the Fabry-Perot cavity length. Further, the sliding distance of the measuring probe can be calculated after the variation of the Fabry-Perot cavity length measured in according with the Fabry-Perot principle.

  • Publication number: 20170219343
    Abstract: The present invention provides a Fabry-Perot sensor for measuring inclination. Wherein the present inclinometer is fixed on a static detected object in application use, the mass block is flexibly connected to the top plate, thus the line between the center of gravity of the mass block and the connecting point on the top plate is perpendicular to the horizontal plane; a Fabry-Perot cavity is formed between the reflecting surface disposed at one end of the mass block and the end of the optic fiber. The detected object will be in a static state after tilting, the line between the center of gravity of the mass block and its connecting point on the top plate is still perpendicular to the level plane and the F-P cavity length will have a variation. Then the change of cavity length can be measured in accordance with the Fabry-Perot principle, thereby the tilting angle of the mass block is able to be further measured. Then the tilting angle is also the inclination of the detected object.
