摘要： 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.

摘要： 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.
