  • 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: 20130122242
    Abstract: A cellucotton having a vertical structure that enables bi-directional elasticity, a production device and a method thereof are disclosed. During the production of the cellucotton having a vertical structure by lapping and stacking of fiber layers (3), multiple gaps are created in the longitudinal direction along the fiber layers, thereby enabling elasticity in the longitudinal direction; and disposed on the cellucotton having a vertical structure produced by lapping and stacking on the fiber layer are multiple fiber grooves (31), the fiber grooves enable elasticity in the transverse direction. The cellucotton has good elasticity in the longitudinal and transverse directions, and can therefore be used for car seat cushions, sofas, and women's underwear to avoid deformation arising from unidirectional expansions and contractions.
