This paper includes hvo different phase selectors that allow high-resolution selection of clock phase from a ring oscillator, one which uses minimum hardware, and one which provides minimum phase variation. Although the idea of using a ring oscillator PLL to provide high-resolution control of clock phase is not new, we believe that o;r explicit description of the logic required to implement the required control is new.
