  • Patent number: 7715297
    Abstract: An optical pickup apparatus and method for recording and/or reproducing information onto and/or from optical discs having diverse specifications. Particularly, a diffraction grating for use in the optical pickup apparatus includes a substrate for refracting an output beam from a laser diode at a predetermined refractive index, a liquid crystal for refracting the beam, which is transmitted through the substrate, at a different refractive index and direction according to a track pitch of the optical disc, an electrode material for supplying power to the liquid crystal, and a switch for controlling power supply to the electrode material. Electrode materials are aligned with various spacing in order to change the refractive index of the liquid crystal according to the wavelength of a laser and the specification of an optical disc used. Also, power supply to the electrode materials is controlled depending on the optical disc specification.

  • Publication number: 20100033226
    Abstract: A level shifter, or method, producing a final output from a driver supplied by a high-side source driver providing VDD or common, and a low-side source driver providing common or VSS. A delay is introduced to prevent a source driver output at common from beginning to transition toward a supply rail until a delaying source driver at a rail begins transitioning toward common. The level shifter may be single-ended or differential, and the delaying source driver may be coupled to the same final output driver as is the delayed source driver, or may be coupled to a different final output driver. The level shifter may have a second level shifter front end stage, which may have high-side and low-side intermediate source driver outputs coupled by a capacitor, and/or may couple one of the supplies to all intermediate source drivers via a common impedance or current limit Zs.
