Abstract
A phase interpolator circuit that produces 2 phase resolution elements using a control signal that has less than m bits. The circuit combines the function of a divide-by-N circuit with a phase interpolation circuit enabled by the use of a higher-speed clock as an input. By performing phase interpolation at a high speed and then slowing down the speed for the subsequent circuits, the phase resolution increases and fewer control bits are required.
