  • Patent number: 10771234
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive an otw signal that is associated with low-path pass information and transmission data. The apparatus may apply a cost function and an update function to the otw signal prior to sending the otw signal to an oscillator. The apparatus may determine a correction factor for use in estimating a gain of the oscillator based at least in part on an output of the update function.

  • Patent number: 10644926
    Abstract: Methods, systems, and devices for wireless communications are described. The method may include identifying phase information generated from modulation information, mapping the phase information by mapping a second phase point located in a second quadrant to a first phase point of a first quadrant, where the first phase point may be associated with a phase trajectory of the phase information, synthesizing the mapped phase information associated with the phase trajectory based on mapping the phase information, rotating the phase trajectory based on a phase-plane rotation value associated with mapping the phase information, and generating a modulated signal associated with a carrier frequency based on mapping the phase information and rotating the phase trajectory.

  • Patent number: 10432267
    Abstract: Exemplary systems, apparatus, and methods described herein may improve a scan process for near field communications, such as IEEE 802.15.4. The improvements may include, during the scan process, performing one of increasing a current of a voltage controlled oscillator (VCO)/digitally controlled oscillator (DCO) of a second wireless device, reducing a bandwidth of a phased locked loop, increasing the bandwidth of the phased locked loop, changing a reference frequency of the phased locked loop, or dithering the reference frequency.

  • Patent number: 10361745
    Abstract: A wireless communication device is described. The wireless communication device includes a transmit/receive (T/R) switch that is configured with an antenna port coupled to an antenna, a transmitter port coupled to a transmitter and a receiver port coupled to a receiver. The T/R switch selectively connects the transmitter port to the antenna port or the receiver port to the antenna port. The wireless communication device also includes a T/R switch controller that sets the T/R switch to disconnect the transmitter from the antenna when the transmitter is actively transmitting in a high insertion loss mode to reduce power from the transmitter to the antenna.

  • Patent number: 9459292
    Abstract: Aspects of the present disclosure are generally directed to techniques and apparatus for estimating a gain of a VCO in a PLL. In certain aspects, the technique includes calculating a C-V characteristic of a varactor matched to another varactor in the VCO. The technique also includes estimating the gain of the VCO based on the C-V characteristic of the varactor, a tank inductance of the VCO, and an output frequency of the VCO. Aspects of the present disclosure allow for estimating the gain of the VCO while the PLL remains in operation.

  • Patent number: 8964816
    Abstract: A configurable transceiver and method of operation are disclosed that may dynamically switch between a direct-conversion mode and a direct-sampling mode based, at least in part, upon a frequency component of a receive and/or transmit signal. When in the direct-conversion mode, the transceiver may operate as a direct-conversion transceiver, and when in the direct-sampling mode, the transceiver may operate as a direct-sampling transceiver. For some embodiments, a frequency of the receive signal and/or the transmit signal may be compared with a predetermined frequency threshold value to generate a mode signal, and the mode signal may be used to select between the direct-conversion mode and the direct-sampling mode.

  • Patent number: 6181206
    Abstract: By selecting a particular configuration of an input stage of a low noise RF amplifier, an optimal combination of linearity and input matching is achieved upon selecting a certain gain factor from a set of fixed step values. Each input stage configuration defines an input matching network specifically suitable to operate at a certain RF frequency. An RF signal input inductor is selectively associated to an input coupling capacitor, and a second degeneration inductor of a gain transistor of the input stage having a different gain value. The selection of a certain configuration is made through at least one switch through which a bias current generator is switched to the programmably selected input stage.
