Patent number: 6625791Abstract: A method and apparatus for optimizing the insertion of decoupling capacitance onto an integrated circuit is provided. Further, a sliding grid based technique for arraying decoupling capacitors into a white-space of an integrated includes sliding a bounded grid across the white-space in order to determine an optimal decap insertion for the white-space. The bounded grid is slid across the white-space in discrete steps. At each discrete step, a potential decap layout is calculated for the region of the white-space that intersects the bounded grid. After a set of potential decap layouts have been calculated for the white-space, the potential decap layout that yields optimal decap insertion is selected, and decap cells are arrayed into the area(s) of the white-space that are demarcated by the selected decap layout.Type: GrantFiled: May 10, 2002Date of Patent: September 23, 2003Assignee: Sun Microsystems, Inc.Inventors: Sudhakar Bobba, Pradeep Trivedi

Patent number: 6618343Abstract: An optical disk device has an aperture of an objective lens in an incoming path of a beam from a semiconductor laser to an optical disk formed larger than an aperture in a return path from the optical disk or an aperture is varied in recording and in reproduction. This configuration improves recording/reproducing ability since light is focused on an optical disk with high numerical aperture. In addition, since reflected light from the optical disk is detected with low numerical aperture, margins for tilt and defocus are not reduced. Furthermore, since unnecessary signal components contained in the reflected light can be eliminated, a S/N (signal-to-noise ratio) of an information signal also increases. Thus, a high-performance optical disk device can be obtained. Alternatively, by varying the aperture of an objective lens in recording and in reproduction, an optical disk device in which recording density and recording quality are increased without deteriorating reproduction quality can be obtained.Type: GrantFiled: November 9, 1999Date of Patent: September 9, 2003Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Youichi Saitoh, Junichi Asada, Yuichi Takahashi, Seiji Nishiwaki, Kenji Nagashima, Kazuo Momoo, Junji Nagaoka
