  • Patent number: 10735008
    Abstract: A comparator offset voltage self-correction circuit is disclosed. A comparator offset voltage which is caused by the semiconductor process parameter randomness also has randomness. Due to the randomness of the comparator offset voltage, a reference voltage of a parallel comparator in a parallel-conversion-type analog-to-digital converter is uncertain. If the comparator offset voltage is large, the parallel-conversion-type analog-to-digital converter may even have a functional error. The comparator offset voltage self-correction circuit provided in the present invention can correct a random offset voltage of a comparator to meet requirements.

  • Publication number: 20200150308
    Abstract: The invention belongs to the field studying the devices for soil and water conservation. The invention involves a topography-meter host based on integrative mainboards, which dynamically observe the landform in real-time and three-dimensions. The linear laser sources are accurately positioned with Ohm-shaped clamps, so as to emit parallel and equidistant laser-planes projecting onto a terrain in an experiment. The positions of the laser-sources on the mainboards are fixed with the Ohm-shaped clamps. The clamps do not only realize the convenient adjustment of the emission angle and spacing distance of the adjacent laser-sources, but also ensure a high accuracy of the positions and angles of the laser-sources even if the topography-meter host is moved. Several multi-segmented cases are freely spliced to observe the landforms with different heights in real-time.
