  • Patent number: 11967645
    Abstract: A semiconductor device is provided. The semiconductor device includes a substrate, a field plate, a gate electrode, and a first dielectric layer. The substrate has a top surface. The substrate includes a first drift region with a first conductivity type extending from the top surface of the substrate into the substrate, and includes a second drill region with the first conductivity type extending from the top surface of the substrate into the substrate and adjacent to the first drift region. The field plate is over the substrate. The gate electrode has a first portion and a second portion, wherein the first portion of the gate electrode is located over the field plate. The first dielectric layer is between the substrate and the field plate. The first portion of the gate electrode is overlapping with a boundary of the first drift region and the second drift region in the substrate.

  • Patent number: 7903617
    Abstract: A method and system for multi-user wireless communications between a sender and a receiver enables effective blocking of interference signals by other senders and improving the channel data rate. The receiver uses two or more receiving devices, such as antennas or smart antennas, to receive multiple wireless input signals. By performing a noise-transparent autocorrelation matching analysis on the multiple input signals, the receiver derives an anti-interference filter for interference-blocking action, without the need for information of the interfering and its transmission channel. In a multi-user environment, the noise-transparent autocorrelation matching analysis is implemented by the Autocorrelation Division Multiple Access (ADMA) system that includes the design and the implementation of ADMA code, the ADMA encoder, the ADMA algorithm and the ADMA decoder.

  • Patent number: 7376394
    Abstract: A method and system for wireless communications between a sender and a receiver enables effective blocking of interference signals by other senders and improving the channel capacity. The receiver uses two or more receiving devices, such as antennas or smart antennas, to receive multiple wireless input signals. By performing a noise-transparent autocorrelation matching analysis on the multiple input signals, the receiver derives an anti-interference filter for interference-blocking action, without the need for information of the interfering vector. The information derived by the receiver may be further used to control the reception by the receiving devices of the receiver, or transmitted to the sender to control its transmission, such that the signal vector may be set to be parallel to the obtained filtering vector to achieve an enhanced channel capacity that may exceed the limit imposed by the well-known Shannon channel capacity of the original channel.
