  • Patent number: 7932566
    Abstract: An integrated circuit including type-1 cells and a type-2 cell is presented. The type-1 cells have poly lines with a default poly pitch. The type-2 cell has poly lines with a non-default poly pitch. A first boundary region has at least one isolation area that lies between the type-1 cells and the type-2 cell in the X-direction. The first boundary region includes at least one merged dummy poly line, wherein the at least one merged dummy poly line has a first portion that complies with the default poly pitch of the type-1 cells and a second portion that complies with the non-default poly pitch of the type-2 cell.

  • Publication number: 20110018616
    Abstract: A charge pump circuit for biasing a capacitive transducer. The charge pump circuit includes a plurality of parallel arranged transistor-capacitor units each having a bipolar junction transistor with a collector terminal connected to a base terminal and an emitter terminal connected to a capacitor. The charge pump circuit also includes drive circuitry for driving the transistor-capacitor units at a predetermined rate, as well as load current circuitry connected to a last transistor-capacitor unit and configured to determine a load current through the transistor-capacitor units in order to establish a controllable voltage drop across the transistor-capacitor units. Also included is supply circuitry configured to supply the transistor-capacitor units and drive circuitry, the supply circuitry configured to bias a base-emitter voltage of the transistor-capacitor units proportional to the load current so that an output voltage of the charge pump is substantially independent of temperature fluctuations.

  • Patent number: 7821039
    Abstract: An integrated circuit structure includes an integrated circuit structure including a PMOS transistor including a first gate electrode; a first source region; and a first drain region; an NMOS transistor including a second gate electrode, wherein the first gate electrode and the second gate electrode are portions of a gate electrode strip; a second source region; and a second drain region. No additional transistors are formed between the PMOS transistor and the NMOS transistor. The integrated circuit further includes a VDD power rail connected to the first source region; a VSS power rail connected to the second source region; and an interconnection port electrically connected to the gate electrode strip. The interconnection port is on an outer side of a MOS pair region including the PMOS transistor, the NMOS transistor, and the region between the PMOS transistor and the NMOS transistor. The portion of the gate electrode strip in the MOS pair region is substantially straight.

  • Patent number: 7808051
    Abstract: An integrated circuit structure includes a semiconductor substrate; a first active region in the semiconductor substrate; and a second active region in the semiconductor substrate and of an opposite conductivity type than the first active region. A gate electrode strip is over the first and the second active regions and forms a first MOS device and a second MOS device with the first active region and the second active region, respectively. A first spacer bar is in the semiconductor substrate and connected to the first active region. At least a portion of the first spacer bar is adjacent to and spaced apart from a portion of the first active region. A second spacer bar is in the semiconductor substrate and connected to the second active region. At least a portion of the second spacer bar is adjacent to and spaced apart from a portion of the second active region.
