  • Linearly controlled CMOS phase interpolator
    Patent number: 6384653
    Abstract: Method and system for providing a signal with a controllable zero crossing time value. The system provides first and second two-sided triangular wave signals, identical but shifted by a selected fraction f·T of a period T of either triangular signal, and forms a weighted sum of the signals, weighted by A and 1−A, respectively, with 0≦A≦1. In each of two time regions within a period T, a zero crossing time of the sum varies linearly with choice of the value A.
