Abstract
A DPC () includes: a frequency source () for generating a clock signal; a delay line () for receiving the clock signal and generating phase-shifted clock signals at output taps; a digital control device () for generating a control signal; and a windowing and selection circuit for generating the output signal, that includes sequential logic devices () and a combining network. A method for use in a DPC includes: receiving () a control signal based on a desired output signal that identifies a first output tap on the delay line; based on the control signal, selecting () at least two output taps on the delay line for receiving at least two different phase-shifted clock signals; and generating () an output signal based on the control signal and the received phase-shifted clock signals that is substantially the desired output signal.
