METHOD AND APPARATUS FOR A DIGITAL-TO-PHASE CONVERTER |
摘要 |
A DPC (300) includes: a frequency source (310) for generating a clock signal; a delay line (320) for receiving the clock signal and generating phase-shifted clock signals at output taps; a digital control device (330) for generating a control signal; and a windowing and selection circuit for generating the output signal, that includes sequential logic devices (500, 510, 520) and a combining network. A method for use in a DPC includes: receiving (400) 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 (410) at least two output taps on the delay line for receiving at least two different phase-shifted clock signals; and generating (420) an output signal based on the control signal and the received phase-shifted clock signals that is substantially the desired output signal. |
