  • Patent number: 8110414
    Abstract: A method of forming integrated circuits (IC) having at least one metal insulator metal (MIM) capacitor. A bottom electrode is formed on a predetermined region of a semiconductor surface of a substrate. At least one dielectric layer including silicon is formed on the bottom electrode, wherein a thickness of the dielectric layer is <1,000 A. A top electrode layer is formed on the dielectric layer. A patterned masking layer is formed on the top electrode layer. Etching using dry-etching at least in part is used to etch the top electrode layer outside the patterned masking layer to reach the dielectric layer, which removes ?100 A of the thickness of the dielectric layer. The dry etch process includes using a first halogen comprising gas, a second halogen comprising gas that comprises fluorine, and a carrier gas.

  • Patent number: 8111181
    Abstract: An embodiment of the invention provides a single-ended polar transmitting circuit. The single-ended polar transmitting circuit comprises a DAC, a differential-to-single-ended converter, a GmC filter and a load. The GmC filter comprises two gain stages, two filters, two switching devices, a translinear loop and a current mirror. When a second clock signal is high, a first current is conducted through the load, a second switching device and a second gain stage. When a first clock signal is high, a second current is conducted through a first switching device and the second gain stage. The first gain stage has a transconductance Gm1 and the second gain stage has a transconductance Gm2. The bandwidth of the GmC filter is approximately equal to the square root of the quantity (Gm1*Gm2)/(C1*C2). The bandwidth of the GmC filter is substantially a constant value.

  • Patent number: 8111731
    Abstract: A method of transmitting signals in a communication system over at least two time periods including generating a base signal comprising of at least two samples in each time period, selecting a scrambling sequence of length equal to or greater than the number of time periods, scaling all samples in said signal in a time period with one element of said scrambling sequence and transmitting the scaled signal in said time period. Different elements of the scrambling sequence are used to scale the base signal in different time periods. The signal in each time period is obtained by scaling a base signal. The scrambling sequence is preferably a pseudo-random sequence. The step of scaling all samples in said signal in a time period consists of multiplying all samples of said signal with an element of said scrambling sequence.

  • Patent number: 8112684
    Abstract: IEEE 1149.1 Test Access Ports (TAPs) may be utilized at both IC and intellectual property core design levels. TAPs serve as serial communication ports for accessing a variety of embedded circuitry within ICs and cores including; IEEE 1149.1 boundary scan circuitry, built in test circuitry, internal scan circuitry, IEEE 1149.4 mixed signal test circuitry, IEEE P5001 in-circuit emulation circuitry, and IEEE P1532 in-system programming circuitry. Selectable access to TAPs within ICs is desirable since in many instances being able to access only the desired TAP(s) leads to improvements in the way testing, emulation, and programming may be performed within an IC. A TAP linking module is described that allows TAPs embedded within an IC to be selectively accessed using 1149.1 instruction scan operations.

  • Patent number: 8112050
    Abstract: A receiver to recover a signal of interest while consuming reduced power in some scenarios. The receiver contains a in-phase channel processing path and a quadrature phase channeling path for down converting an input signal to an intermediate frequency, and then recovering the signal of interest by further processing of the input signal at intermediate frequency. One of the two paths is turned off upon occurrence of a desired condition, which reduces power consumption. In an embodiment, the condition is that the input signal does not contain an image signal of the signal of interest.

  • Patent number: 8110857
    Abstract: A low noise (1/f) junction field effect transistor (JFET) is disclosed, wherein multiple implants push a conduction path of the transistor away from the surface of a layer upon which the transistor is formed. In this manner, current flow in the conduction path is less likely to be disturbed by defects that may exist at the surface of the layer, thereby mitigating (1/f) noise.

  • Patent number: 8111330
    Abstract: A method and apparatus for an analog-to-digital video signal converter. The converter is controlled by a clock with controllable frequency and phase for sampling an analog signal. A circuit corrects the clock frequency using a period of a columnar frame differences as a function of columnar location. The sampling clock frequency is changed by an amount dependent on the period of the columnar differences. A second measure of the difference between successive frames is computed for a sequence of clock phases. The frequency of the clock is verified using a characteristic of the second measure. The characteristic can be the ratio of the maximum to the minimum of the second measure over selected clock phases. Other characteristics can be used such as a difference of a maximum and a minimum measure.

  • Patent number: 8112652
    Abstract: This invention manages power down and wakeup of shared memories in a multiprocessor system. A register for each shared memory has bits corresponding to each master. When a master wants to power down a memory, it sets its corresponding bit in the register. A hardware power down controller for the memory bank powers the memory bank if any processor signals powering the memory bank. The hardware power down controller for the memory bank powers down the memory bank only if all processor signal powering down the memory bank. The hardware power down controller waits for all masters to set their corresponding bits in the register before initiating power down of the memories. Software running on any processor has a view of the shared memory independent of the other processors and no inter-processor communication is needed.
