  • Publication number: 20140237438
    Abstract: A method of modeling an integrated circuit chip includes generating a model of a bond pad using a design tool running on a computer device. The method also includes connecting a first inductor, a first resistor, and a first set of parallel-resistor-inductor elements in series between a first node and a second node in the model. The method further includes connecting a second inductor, a second resistor, and a second set of parallel-resistor-inductor elements in series between the second node and a third node in the model. The first node corresponds to a first signal port of the bond pad. The second node corresponds to a second signal port of the bond pad.

  • Patent number: 8806419
    Abstract: A method for modeling FinFET width quantization is described. The method includes fitting a FinFET model of a FinFET device to single fin current/voltage characteristics. The FinFET device comprises a plurality of fins. The method includes obtaining statistical data of at least one sample FinFET device. The statistical data includes DIBL data and SS data. The method also includes fitting the FinFET model to a variation in a current to turn off the finFETs device (IOFF) in the statistical data using the DIBL data and the SS data and determining a model for a voltage to turn off the finFETs device (VOFF). The method also includes fitting the FinFET model to the VOFF.

  • Patent number: 8514028
    Abstract: A voltage controlled oscillator (VCO), IC and CMOS IC including the VCO. The VCO includes an LC tank circuit, a pair of cross-coupled devices connected to the tank circuit and driving a pair of buffers. Each of the pair of cross-coupled devices includes a field effect transistor (FET) with an independently controllable body, e.g., the surface layer of a Silicon on Insulator (SOI) chip or the surface well of a multi-well chip. Diodes in the multi-well structure are biased off in each device. The tank circuit is coupled to the buffers solely through the FET drain to body capacitance.
