  • Patent number: 9735765
    Abstract: Embodiments include apparatuses, methods, and systems for jitter equalization and phase error detection. In embodiments, a communication circuit may include a data path to pass a data signal and a clock path to pass a clock signal. A jitter equalizer may be coupled with the data path and/or clock path to provide a programmable delay to the data signal and/or clock signal, respectively. The delay may be determined by a training process in which a supply voltage may be modulated by a modulation frequency. The delay may be dependent on a value of the supply voltage, such as a voltage level and/or jitter frequency component of the supply voltage. A phase error detector is also described that may be used with the communication circuit and/or other embodiments.

  • Publication number: 20170040255
    Abstract: Techniques are disclosed for forming a through-body-via (TBV) isolated coaxial capacitor in a semiconductor die. In some embodiments, a cylindrical capacitor provided using the disclosed techniques may include, for example, a conductive TBV surrounded by a dielectric material and an outer conductor plate. The TBV and outer plate can be formed, for example, so as to be self-aligned with one another in a coaxial arrangement, in accordance with some embodiments. The disclosed capacitor may extend through the body of a host die such that its terminals are accessible on the upper and/or lower surfaces thereof. Thus, in some cases, the host die can be electrically connected with another die to provide a die stack or other three-dimensional integrated circuit (3D IC), in accordance with some embodiments. In some instances, the disclosed capacitor can be utilized, for example, to provide integrated capacitance in a switched-capacitor voltage regulator (SCVR).

  • Patent number: 9513692
    Abstract: A memory controller operable for selective memory access to areas of memory exhibiting different attributes leverages different memory capabilities that vary access speed, retention time and power consumption, among others. Different areas of memory have different attributes while remaining available to applications as a single contiguous range of addressable memory. The memory controller employs an operating mode that identifies operational priorities for a computing device, such as speed, power conservation, or efficiency. The memory controller identifies an area of memory based on an expected usage of the data stored in the area, for example an access frequency indicating future retrieval. The memory controller therefore selects areas of memory based on the operating mode and the expected usage of data to be stored in the area according to a heuristic that favors areas of memory based on those exhibiting attributes having a high correspondence to the expected usage of the data.

  • Publication number: 20160089075
    Abstract: Technologies for the sensing of biofeedback signals of a user include a body area network (BAN) system comprising one or more biofeedback sensors and one or more BAN controllers. The biofeedback sensors are configured to sense BAN signals, which may include biofeedback signals and body-coupled communication (BCC) signals. To facilitate communication, the biofeedback sensors may demultiplex the sensed BAN signals into biofeedback signals and incoming BCC signals. Similarly, the biofeedback sensors may multiplex outgoing BCC signals with sensed biofeedback signals. The BAN controller may communicate in a similar manner. Additionally, the BAN controller may process incoming BCC signals and provide feedback to the user based on BCC signals received from the biofeedback sensors.
