Abstract: 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 (Vclk) to a first and second output signal (Vn,Vp), where the first and second output signals (Vn,Vp) 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 (Vn,Vp), and outputs first and second balanced output signals (V+,V?). The buffer stage (26) is electrically connected to the phase balancing stage (24) for shaping the first and second balanced output signals (V+,V?). The single-to-differential converter (20) is operable over a substantially large bandwidth and achieves low-power consumption and good phase noise performance.
