In one embodiment, a phase interpolator with a phase range of n degrees, where 0<n≰360, and having m reference signals, where m≧2, and a control signal as input, and producing an output signal with a phase within the phase range using one or more of the m reference signals based on a control code provided by the control signal. The phase interpolator comprises one or more circuits configured to: divide the phase range of n degrees into k sections, wherein k>m; and for each of the k sections, select a relative gain of one or more weights assigned to the one or more reference signals, respectively, with respect to the control code provided by the control signal. |
