摘要： Certain aspects of a method and system for mitigating effects of pulling in multiple phase locked loops in multi-standard systems may include selecting an input frequency range of operation at a voltage controlled oscillator based on a particular wireless band of operation in a system that handles a first wireless communication protocol and a second wireless communication protocol. An image rejection mixer may be enabled to generate an output signal for the particular wireless band of operation based on mixing a plurality of received signals within a selected frequency range. An in-phase (I) component and a quadrature (Q) component of the generated output signal may be generated by utilizing a RC-CR quadrature network.

摘要： Certain aspects of a method and system for independent in-phase (I) and quadrature (Q) loop amplitude control for quadrature generators may include determining an amplitude voltage associated with an in-phase (I) component and a quadrature (Q) component of a generated signal. A DC reference voltage associated with the I component and the Q component may be determined. The determined amplitude voltage may be compared with the determined reference voltage to generate a control signal. The amplitude mismatch between the I component and the Q component may be compensated by controlling a biasing current of one or more programmable buffers associated with one or both of the I component and the Q component, based on the generated control signal.

摘要： A method and system for calibrating a plurality of modules in a communication system is provided. The method may include selecting a plurality of modules with at least one output signal and calibrating an amplitude of each selected module to be within a specified range if the amplitude is out of the specified range via a gain control processing circuit of the selected module, wherein the plurality of modules may be calibrated in an order starting with a first module located at an input of a signal path and ending with a module located at an output of the signal path. The DC component and amplitude of the envelope of the output signal may be detected by circuitry within the selected module. Muxes may be utilized to route the DC component and amplitude of the envelope to a feedback control processing circuit.
