  • Patent number: 9980197
    Abstract: A method of operating a baseband processing unit for a wake-up receiver. The method includes receiving a signal from a transmitting device that contains a pseudo-random code. The method further includes adding a local pseudo-random code associated with a first correlator of the processing unit with a local pseudo-random code associated with a second correlator of the processing unit to generate a summed local pseudo-random code, and correlating by the first correlator the received pseudo-random code with the summed local pseudo-random code. The method still further includes comparing an output of the first correlator with a predetermined threshold, and determining whether or not to generate a wake-up signal based on the comparison. A baseband processing unit for performing this methodology is also provided.

  • Patent number: 9627042
    Abstract: A static random access memory (SRAM) cell is provided with improved write margin. The SRAM cell includes: a pair of inverters cross coupled to each other and forming two storage nodes; read access switches electrically coupled between a read bit line and the two storage nodes; write access switches electrically coupled between write bit lines and two storage nodes; and supply switches electrically coupled between a supply voltage and the pair of inverters and operable, in response to a signal on at least one of the write bit lines, to selectively connect the supply voltage to at least one of the inverters in the pair of inverters. During a write operation, the supply switches operate to cut off the supply voltage to the inverter in the pair of inverters having a charged state.
