Abstract: A low noise amplifier (LNA) reduces matching and switch noise. The LNA includes a main radio frequency signal path, an auxiliary radio frequency signal path and a phase shifter. The main path includes a first transistor and an inductor. The inductor is positioned between an input port of the LNA and the first transistor. The first transistor receives an input radio frequency signal via the inductor and provides a first amplified signal based on the input radio frequency signal. The auxiliary radio frequency signal path provides a second amplified signal for a noise cancellation mode based on the input radio frequency signal. The phase shifter applies a phase shift to an output signal of the LNA based on the first amplified signal and the second amplified signal.

Abstract: Methods and apparatuses are described that facilitate data communication across a serial bus. In one configuration, a transmitter configures a plurality of devices by assigning one or more trigger registers to each device of the plurality of devices and sends to each device a trigger register assignment command indicating a trigger register assigned to a device and identifying a trigger corresponding to the device. The transmitter then addresses a packet to an assigned trigger register and generates a bit-index field in the packet. Bits in the bit-index field respectively represent triggers corresponding to devices associated with the assigned trigger register, wherein each bit indicates whether one or more corresponding devices are enabled for operation. The transmitter then sends the packet to the plurality of devices via the serial bus.

Abstract: A method of selecting a mode for an SPS receiver includes selecting either a first mode or a second mode for the SPS receiver based on a comparison between an output power of a communications transceiver and a mode switch point wherein the mode switch point is a power value. The first mode corresponds to a first bias current value of the SPS receiver, the second mode corresponds to a second bias current value of the SPS receiver, and the first bias current value is different from the second bias current value.
