Abstract: A subordinate device participates in address assignment through iterative communication with a host device. The subordinate device receives a first broadcast command over a multidrop serial bus, decouples a daisy chain input of the subordinate device from a daisy chain output of the subordinate device, receives a second broadcast command over the multidrop serial bus, responds to the second broadcast command when a signal received through the daisy chain input is in an active state, ignores the second broadcast command when the signal received through the daisy chain input is in an inactive state, and ignores subsequent broadcast commands after responding to the second broadcast command. Responding to the second broadcast command includes configuring a unique device identifier of the subordinate device using an address provided in the second broadcast command, and coupling the daisy chain input of the subordinate device to the daisy chain output of the subordinate device.

Abstract: A UE may attempt, based on a first mode, to identify a first opportunity within a preconfigured time period for a measurement associated with at least one SCC when the at least one SCC is deactivated at the UE and the measurement associated with the at least one SCC is due based on a scheduling. Based on the first mode, a radio of the UE may not be tuned to the at least one SCC when the at least one SCC is deactivated at the UE and no measurement associated with the at least one SCC is being performed at the UE. The UE may perform, if the first opportunity is identified within the preconfigured time period, the measurement associated with the at least one SCC at the identified first opportunity.

Abstract: An aspect includes a filtering method including operating a first filter to filter a first input signal to generate a first output signal; operating a second filter to filter a second input signal to generate a second output signal; and merging at least a portion of the second filter with the first filter to filter a third input signal to generate a third output signal. Another aspect includes a filtering method including operating switching devices to configure a filter with a first set of pole(s); filtering a first input signal to generate a first output signal with the filter configured with the first set of pole(s); operating the switching devices to configure the filter with a second set of poles; and filtering a second input signal to generate a second output signal with the filter configured with the second set of poles.

Abstract: A data communication apparatus comprises a line driver configured to couple the data communication apparatus to a 1-wire serial bus; and a controller configured to: transmit a plurality of synchronization pulses over the 1-wire serial bus after a sequence start condition (SSC) has been transmitted over the 1-wire serial bus, the plurality of synchronization pulses being configured to synchronize one or more receiving devices coupled to the 1-wire serial bus to an untransmitted transmit clock signal; initiate an interrupt handling procedure when the plurality of synchronization pulses is encoded with a first value; and initiate a read transaction or a write transaction with at least one of the one or more receiving devices coupled to the 1-wire serial bus when the plurality of synchronization pulses is encoded with a second value.

Abstract: A user equipment (UE) is provided that detunes a receive antenna while a transmit antenna transmits. To determine the detuning, the UE first transmits a signal through the transmit antenna while the receive antenna is sequentially coupled through known loads. At each load, the UE determines an input reflection coefficient for a transmit path to the transmit antenna. Based upon the known loads and the corresponding input reflection coefficients, the UE determines a load to couple to the receive antenna to perform the detuning.

Abstract: A receive clock generated at a receiver coupled to a one-wire bus is synchronized in each clock cycle, permitting reception of a data frame of unlimited length without clock overrun or underrun. A base clock signal provided by an oscillator is passed by a clock gating circuit while the clock gating circuit is enabled. A counter counts positive and negative edges in an output of the clock gating circuit. The clock gating circuit is disabled when an output of the counter indicates a preconfigured maximum count value. An edge synchronization circuit that synchronizes edges in the base clock signal with edges in a data signal received over the one-wire bus ignores edges in the data signal while the counter output has a value that is less than the maximum count value, and resets the counter in response to an edge detected in the data signal received over the one-wire bus.

Abstract: Aspects of the disclosure relate to devices, wireless communication apparatuses, methods, and circuitry implementing a low noise amplifier (LNA) with phase-shifting circuitry to achieve a continuous phase at the output of the LNA. One aspect is an amplifier including a high gain active path comprising active circuitry, and a low gain path comprising passive circuitry and phase-shifting circuitry. In one or more aspects, the phase-shifting circuitry is configured to shift a phase of an input signal within the low gain path such that the phase of an output signal outputted from the low gain path approximately matches a phase of an output signal outputted from the high gain active path. In at least one aspect, a gain of the high gain active path is higher than a gain of the low gain passive path.
