Abstract: A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other wireless communication device(s) and to generate and process signals for such communications.

Abstract: Frame formatting for communications within single user, multiple user, multiple access, and/or MIMO wireless communications. A signal is processed within a communication device using at least two respective downclocking ratios (e.g., a first downclocking ratio applied to a first portion of the signal such as a frame or packet extracted there from, a second downclocking ratio applied to a second portion of the signal). Alternatively, a signal is divided into more than two respective portions, and different respective downclocking ratios are applied to those different respective portions (e.g., a first downclocking ratio applied to a first portion of the signal, and so on up to an n-th downclocking ratio applied to an n-th portion of the signal). Some implementations apply a singular or common downclocking ratio to more than one portion of the signal (which may be contiguous/adjacent or non-contiguous/non-adjacent within the signal).

In an embodiment, the dual output path architecture includes an LNA driving a low level of impedance in a low voltage gain path, thus achieving high linearity in the presence of large blockers, and driving a high level of impedance in a high voltage gain path to increase the LNA's voltage gain and minimize performance degradation due to a noisier, low power receiver front-end chain following the LNA. The present disclosure is further directed to a local oscillator (LO) offset circuit with low power and reduced spur generation.

Abstract: In some aspects, the disclosure is directed to methods and systems for virtual angle-of-arrival (AoA) or angle-of-departure (AoD) tracking for virtually tracking multiple Targets. The wireless devices (e.g. Tracker and Targets) may participate in a mesh configuration and share data within the mesh. A first device may purport to be a virtual tracker, while acting as an AoA or Angle of Departure (AoD) Target. The devices being tracked (e.g. virtual targets), may instead operate as Trackers. Processor- and energy-intensive calculations may be distributed to the virtual targets and transmitted via the mesh for aggregation at the virtual tracker.

Abstract: Transconductance (gm)-cell based circuitry is well suited for low power, low voltage complementary metal oxide silicon (CMOS) design in deep sub micro technology. This circuitry includes a gm cell as the basic building block. As such, it is desirable to have the transconductance of the gm cell to be constant against temperature and process corners. The present disclosure describes various gm-cell based circuitry having a controllable transconductance. Preferably, the controllable transconductance can be selectively controlled to be equal to the inverse of the value of an on-chip resistor. For example, the gm-cell based circuitry can sense the transconductance of an internal replica unit and can use negative feedback circuitry to cause this transconductance to be approximately equal a value of an on-chip resistor. However, in some situations, a value of this on-chip resistor is not accurately controlled.

Abstract: A monitoring device may monitor its proximity to a monitored station. The monitored station may transmit a proximity indicator to the monitoring device. For example, the proximity indicator may include the received signal strength of a signal sent by the monitored station. Wireless interface control circuitry at the monitoring device may monitor the status of the proximity indicator for changes. If one or more criteria set by an application processor are met by a detected change, the wireless interface control circuitry may send a status update to the application processor. In the criteria are not met, generation of the status update may be forgone. The application processor need not monitor the proximity indicator status and may remain in a reduced power consumption mode for longer periods.
