INCREASED SYNTHESIZER PERFORMANCE IN CARRIER AGGREGATION/MULTIPLE-INPUT, MULTIPLE-OUTPUT SYSTEMS |
摘要 |
Certain aspects of the present disclosure provide methods and apparatus for using multiple voltage-controlled oscillators (VCOs) to increase frequency synthesizer performance, such as in stringent multiple-input, multiple-output (MIMO) modes. One example apparatus capable of generating oscillating signals generally includes a first VCO, a second VCO, and connection circuitry configured to connect the second VCO in parallel with the first VCO if a phase-locked loop (PLL) associated with the second VCO is idle. |
