  • Patent number: 9368411
    Abstract: A SOI substrate layer formed of a silicon semiconductor material includes adjacent first and second regions. A portion of the silicon substrate layer in the second region is removed such that the second region retains a bottom portion made of the silicon semiconductor material. An epitaxial growth of a silicon-germanium semiconductor material is made on the bottom portion to produce a silicon-germanium region. The silicon region is patterned to define a first fin structure of a FinFET of a first (for example, n-channel) conductivity type. The silicon-germanium region is also patterned to define a second fin structure of a FinFET of a second (for example, p-channel) conductivity type.

    Abstract: A FinFET transistor includes a fin of semiconductor material with a transistor gate electrode extending over a channel region. Raised source and drain regions of first epitaxial growth material extending from the fin on either side of the transistor gate electrode. Source and drain contact openings extend through a pre-metallization dielectric material to reach the raised source and drain regions. Source and drain contact regions of second epitaxial growth material extend from the first epitaxial growth material at the bottom of the source and drain contact openings. A metal material fills the source and drain contact openings to form source and drain contacts, respectively, with the source and drain contact regions. The drain contact region may be offset from the transistor gate electrode by an offset distance sufficient to provide a laterally diffused metal oxide semiconductor (LDMOS) configuration within the raised source region of first epitaxial growth material.

  • Patent number: 9362855
    Abstract: An embodiment of a motor controller includes first and second supply nodes, a motor-coil node, an isolator, a motor driver, and a motor position signal generator. The isolator is coupled between the first and second supply nodes, and the motor driver is coupled to the second supply node and to the motor-coil node. The motor position signal generator is coupled to the isolator and is operable to generate, in response to the isolator, a motor-position signal that is related to a position of a motor having at least one coil coupled to the motor-coil node. By generating the motor-position signal in response to the isolator, the motor controller or another circuit may determine the at-rest or low-speed position of a motor without using an external coil-current-sense circuit.

The content of the fields is changed from the standard 802.11 arrangement to meet of the needs of networks such as Sub-1 GHz networks, including those of the 802.11ah standard, and sensor networks with a large number of stations transmitting at low data rates. In some embodiments, MAC header fields are reduced from standard 802.11 header fields by using only two fields for addressing and eliminating standard fields that are not used in sensor networks.

  • Publication number: 20160149500
    Abstract: A fly-back type switched current regulator includes a primary transformer winding coupled to receive a rectified DC signal derived from an AC signal. The drain of a power transistor is coupled to the primary winding, with the source of the power transistor coupled to an input of a comparison circuit and a primary transformer winding sense resistor. A control terminal of the power transistor is coupled to an output of the comparison circuit. A capacitor stores a variable reference signal for application at a first capacitor terminal to another input of the differential circuit. The variable reference signal is compared to a winding current signal generated by the sense resistor by the comparison circuit. An injection circuit applies an AC signal derived from the rectified DC signal to a second terminal of the capacitor so as to modulate the stored variable reference signal. The regulator is coupled to drive LEDs.

  • Patent number: 9338033
    Abstract: An embodiment of a receiver includes signal- and data-recovery units. The signal-recovery unit is configured to recover a first component of a first signal that is received simultaneously with a second signal having a second component, the first and second components including approximately a frequency. And the data-recovery unit is configured to recover data from the first signal in response to the recovered first component. For example, such a receiver may be able to receive simultaneously, and over the same channel space, multiple orthogonal-frequency-division-multiplexed (OFDM) signals that include one or more of the same subcarrier frequencies, and to recover data from one or more of the OFDM signals despite the frequency overlap. A receiver with this capability may allow an increase in the effective bandwidth of the channel space, and thus may allow more devices (e.g., smart phones) to simultaneously share the same channel space.

  • Patent number: 9337079
    Abstract: Isolation trenches are etched through an active silicon layer overlying a buried oxide on a substrate into the substrate, and through any pad dielectric(s) on the active silicon layer. Lateral epitaxial growth of the active silicon layer forms protrusions into the isolation trenches to a lateral distance of at least about 5 nanometers, and portions of the isolation trenches around the protrusions are filled with dielectric. Raised source/drain regions are formed on portions of the active silicon layer including a dielectric. As a result, misaligned contacts passing around edges of the raised source/drain regions remain spaced apart from sidewalls of the substrate in the isolation trenches.
