Patent number: 6177829Abstract: A charge pump uses switching transistors including a PMOS transistor (P1), a first transistor (N1), and a second transistor (N2) instead of diodes (D1, D2) to control the transfer of charge from a pump capacitor (14) to a storage capacitor (20). The voltage (60) at the storage capacitor (20) is applied to a level shifter (13) and to the source of the PMOS transistor (P1) which, in turn, biases the first transistor (N1) during low state of an oscillating waveform (30B). A supply rail (140) charges the pump capacitor (14) when the first transistor (N1) is in its active region during the low state of the oscillating waveform (30B) and turns OFF during the high state of the waveform (30B) causing the charge on the pump capacitor (14) to be transferred to the storage capacitor (20). The level shifter (13) is used to synchronize the oscillating waveform (30B) so that no charge is lost from the pump capacitor (14) back to the supply and minimal charge is conducted through a parasitic diode (55).Type: GrantFiled: November 19, 1998Date of Patent: January 23, 2001Assignee: Texas Instruments IncorporatedInventors: Roy Clifton Jones, III, Wayne T. Chen, David Cotton, Baoson Nguyen

Patent number: 6021015Abstract: A system for driving hard disk drive spindle and actuator motors is disclosed. The system comprises a spindle motor control circuit (120), a spindle motor power circuit (210), an actuator motor control circuit (110), and an actuator motor power circuit (210). The spindle motor control circuit (120) and the actuator motor control circuit (110) are formed on a first substrate (100). The spindle motor power circuit (210) and the actuator motor power circuit (220) are formed on a second substrate (200). The system also includes at least one disk (22) attached to a rotatable spindle (21), a spindle motor (400) for receiving and being energized by the spindle motor power signals, and for controlling the rotation of the spindle (21), a plurality of disk read heads (12) adjacent to the disks (22), and an actuator motor (300) for receiving and being energized by the actuator motor power signals, and for controlling the position of the disk read heads (12).Type: GrantFiled: May 21, 1997Date of Patent: February 1, 2000Assignee: Texas Instruments IncorporatedInventors: Edward N. Jeffrey, William R. Krenik, David Cotton, Dennis V. Hahn, Shaibal Barua, Roy C. Jones, III

Patent number: 5859456Abstract: An interconnection structure and method for a multiple transistor integrated circuit power device is disclosed. A power integrated circuit is formed of a plurality of source and drain diffusion regions to be coupled together to form the source and drain of multiple LDMOS transistors. Each diffusion region has a first metal layer stripe formed over it and in electrical contact with it. A second metal layer conductor is formed over a plurality of the first metal layer stripes, and selectively contacts the first metal layer stripes to form source and drain busses. Polysilicon gate busses are provided as well. A thick third metal layer is then formed over each second metal layer bus, either physically contacting it or selectively electrically contacting it. The thick third level metal is fabricated of a highly conductive material, such as copper. The resulting on resistance for the transistors on the integrated circuit is substantially reduced by the use of the thick third metal layer.Type: GrantFiled: September 9, 1996Date of Patent: January 12, 1999Assignee: Texas Instruments IncorporatedInventors: Taylor R. Efland, David Cotton, Dale J. Skelton

Patent number: 5719423Abstract: A high current power transistor is provided that comprises a drain region that includes a highly-doped drain region (54) and a lightly-doped drain region (50). The channel region (52) is activated by a gate conductor (32). The channel region separates the lightly-doped drain region (50) from a D-well region (40). A sidewall insulator body (44) is used to form the lightly-doped drain region (50) and the lightly-doped drain region (54). The transistor is formed in an active region (20) which comprises a portion of an n-type epitaxial layer (12) formed outwardly from a p-type substrate (10). The isolation structures (14) and (16) as well as the epitaxial layer (12) provides for a transistor that can be used in both source follower and common source configurations.Type: GrantFiled: August 28, 1996Date of Patent: February 17, 1998Assignee: Texas Instruments IncorporatedInventors: James R.

Patent number: 5336323Abstract: Wallpaper dispenser for automatically hydrating a film of glue pre-applied to one side of a roll of wallpaper. The dispenser includes a reservoir having a roll of wallpaper rotatably supported thereover and a roller for guiding the wallpaper within a quantity of water contained within the reservoir. A ramp is provided for cutting the wallpaper and includes a cutting ridge along which a cutting member is drawn to cut the wallpaper perpendicular to the length thereof. A tape measure and means for securing the tape measure adjacent the ridge are provided to indicate the point, forwardly of the ridge, adjacent which the forward margin of the wallpaper should be positioned. A slidable member is provided to automatically align the pattern on one strip of wallpaper with the same pattern on a previously cut strip when the strips are positioned in laterally adjacent relation and with the top margins thereof in alignment.Type: GrantFiled: June 5, 1992Date of Patent: August 9, 1994Assignee: Paper Draper, Inc.Inventors: David Cotton, Adelbert H.
