1. A method for up-converting a baseband signal, comprising the steps of:

  • (1) receiving the baseband signal;

    (2) differentially sampling the baseband signal according to a first control signal and a second control signal resulting in a plurality of harmonic images that are each representative of the baseband signal, wherein said first and second control signals have pulse widths that improve energy transfer to a desired harmonic image of said plurality of harmonics; and

    (3) minimizing DC offset voltages between sampling modules during step (2), and thereby minimizing carrier insertion in said harmonic images.
