摘要：
A method is provided for generating local oscillator signals for a mixer. The method includes providing a reference frequency signal and generating a differential in-phase signal and a differential quadrature signal from the reference frequency signal. The method further includes re-clocking each of the differential in-phase and differential quadrature signals using the reference frequency signal. The re-clocked differential in-phase and differential quadrature signals are then provided as the local oscillator signals for the mixer.
