    Abstract: A multi-mode receiver is disclosed that is reconfigurable to share a local oscillator signal in diversity mode to save power consumption. In an exemplary embodiment, an apparatus includes a primary receiver having a primary mixer configured to down-convert a primary signal and a secondary mixer configured to down-convert a secondary signal in carrier aggregation mode. The apparatus also includes a supplemental mixer that uses a shared primary local oscillator (LO) signal generated by a shared primary frequency synthesizer in diversity mode to reduce power consumption. The apparatus further includes a controller configured to disable the secondary mixer and to enable the supplemental mixer to down-convert the secondary signal when operating in the diversity mode.

    Abstract: A method and apparatus for providing an oscillating signal within a transmitter/receiver circuit is described. The transmitter/receiver circuit may include an oscillator that generates an oscillating signal that may be provided to a low power, low gain mixer of the transmitter/receiver circuit along a shorter circuit path that includes low power circuitry, such as low power buffers and low power frequency dividers. The oscillating signal may also be provided to a high power, high gain mixer along a longer circuit path that includes high power circuitry, such as high power buffers and high power frequency dividers. Specifically, the low power circuitry is adapted to consume less power in an ON state than the high power circuitry in an ON state, and the shorter circuit path has a shorter electrical path length than the longer circuit path.

    Abstract: Certain aspects of the present disclosure provide methods and apparatus for generating local oscillator (LO) signals for multiple receive chains. One example circuit for generating first and second signals generally includes a first voltage controlled oscillator (VCO) configured to output the first signal at a first frequency and associated with a first receive chain for receiving a first carrier of an aggregated resource; and a second VCO configured to output the second signal at a second frequency and associated with a second receive chain for receiving a second carrier of the aggregated resource. The second frequency is different than the first frequency. In this manner, pulling or coupling between the two VCOs may be avoided, even if the two VCOs are implemented on the same radio frequency integrated circuit (RFIC).

    Abstract: A method for dividing the frequency of a signal using a configurable dividing ratio is disclosed. An input signal with a first frequency is received at clocked switches in a frequency divider with a configurable dividing ratio. Non-clocked switches inside the frequency divider are operated to select one of multiple dividing ratios. An output signal is output with a second frequency that is the first frequency divided by the selected dividing ratio.
