Abstract
Methods, circuits, and apparatus for correcting the phase of a clock signal are presented. In one method, an operation is included for receiving, from a plurality of input lines, a plurality of input clock signals with respective input clock phases. The input clock phases form an ordered sequence of clock phases. The method further includes an operation for transmitting, over a plurality of output lines, a plurality of output clock signals with respective output clock phases. The input and output lines are coupled to a serially coupled ring of resistors, where each resistor in the ring has a terminal coupled to an input line and the other terminal coupled to an output line. Further, each output clock phase has a value that is between successive input clock phases of the ordered sequence of clock phases.
