Techniques for dividing frequencies of periodic signals |
| 摘要 |
A frequency divider circuit includes an adder circuit, multiplexer circuits, and a phase interpolator circuit. The adder circuit generates a summed value. The multiplexer circuits receive first periodic signals and generate second periodic signals by selecting among the first periodic signals based on the summed value. The phase interpolator circuit generates a third periodic signal using a weighted average of the second periodic signals that is determined based on the summed value. |

1. A frequency divider circuit comprising:
an adder circuit to generate a summed value; first multiplexer circuits to receive first periodic signals and to generate second periodic signals by selecting among the first periodic signals based on the summed value; and a first phase interpolator circuit to generate a third periodic signal using a weighted average of the second periodic signals that is determined based on the summed value. |
