A method and apparatus for single-to-differential conversion includes a single-to-differential stage ( 22 ), a phase balancing stage ( 24 ), and a buffer stage ( 26 ). The single-to-differential stage ( 22 ) converts a single input signal (V<SUB>clk</SUB>) to a first and second output signal (V<SUB>n</SUB>,V<SUB>p</SUB>), where the first and second output signals (V<SUB>n</SUB>,V<SUB>p</SUB>) correspond to one another. The phase balancing stage ( 24 ) is electrically connected to the single-to-differential stage ( 22 ), balances and receives the first and second output signals (V<SUB>n</SUB>,V<SUB>p</SUB>), and outputs first and second balanced output signals (V<SUB>+</SUB>,V<SUB>-</SUB>). The buffer stage ( 26 ) is electrically connected to the phase balancing stage ( 24 ) for shaping the first and second balanced output signals (V<SUB>+</SUB>,V<SUB>-</SUB>). The single-to-differential converter ( 20 ) is operable over a substantially large bandwidth and achieves low-power consumption and good phase noise performance.
