  • Patent number: 12294032
    Abstract: A semiconductor device includes a Schottky diode on a silicon-on-insulator (SOI) substrate. The Schottky diode includes a guard ring with a first guard ring segment contacting a barrier region on a first lateral side of the barrier region, and a second guard ring segment contacting the barrier region on a second, opposite, lateral side of the barrier region. The first and second guard ring segments extend deeper in the semiconductor layer than the barrier region. The Schottky diode further includes a drift region contacting the barrier region, and may include a buried layer having the same conductivity type as the barrier region, extending at least partway under the drift region. The barrier region is isolated from the substrate dielectric layer of the SOI substrate by an isolation region having the same conductivity type as the guard ring. A metal containing layer is formed on the barrier region.

  • Patent number: 12288069
    Abstract: A streaming engine employed in a digital signal processor specifies a fixed read only data stream. Once fetched the data stream is stored in two head registers for presentation to functional units in the fixed order. Data use by the functional unit is preferably controlled using the input operand fields of the corresponding instruction. A first read only operand coding supplies data from the first head register. A first read/advance operand coding supplies data from the first head register and also advances the stream to the next sequential data elements. Corresponding second read only operand coding and second read/advance operand coding operate similarly with the second head register. A third read only operand coding supplies double width data from both head registers.

  • Patent number: 12289084
    Abstract: Examples of amplifier circuitry regulate a transconductance value (Gm) of operational transconductance amplifiers (OTAs) in the amplifier to be approximately the same, which value is based on a supply voltage and a reference voltage applied to a reference OTA and the internal resistance of the reference OTA. The reference OTA generates an output current based on Gm and the reference voltage, which current is compared to current generated by the supply voltage and internal resistance of the reference OTA. A tail current transistor of each of the reference OTA and a main OTA that mirrors the Gm of the reference OTA provide a tail current feedback path by which Gm is regulated. Amplifying circuitry is coupled to the main OTA to receive current signals. Based on the received current signals, amplifying circuitry generates a differential output voltage signal. The gain of the amplifying circuitry is proportional to the supply voltage and remains relatively constant across process temperature variations.

  • Patent number: 12273852
    Abstract: Using a phase interferometry method which utilizes both amplitude and phase allows the determination and estimation of multipath signals. To determine the location of an object, a signal that contains sufficient information to allow determination of both amplitude and phase, like a packet that includes a sinewave portion, is provided from a master device. A slave device measures the phase and amplitude of the received packet and returns this information to the master device. The slave device returns a packet to the master that contains a similar sinewave portion to allow the master device to determine the phase and amplitude of the received signals. Based on the two sets of amplitude and phase of the RF signals, the master device utilizes a fast Fourier transform or techniques like multiple signal classification to determine the indicated distance for each path and thus more accurately determines a location of the slave device.
