DIVIDING A FREQUENCY BY 1.5 TO PRODUCE A QUADRATURE SIGNAL |
摘要 |
An apparatus for dividing a frequency by 1.5 to produce a quadrature signal is disclosed. The apparatus includes a divider that receives a differential input signal with a first frequency and two phases and creates a six-phase signal at a second frequency. The second frequency is the first frequency divided by 3. The apparatus also includes precision phase rotation circuitry that receives the six-phase signal and produces an eight-phase signal. The apparatus also includes a doubler that receives the eight-phase signal and produces a quadrature signal. The quadrature signal has a third frequency that is the first frequency divided by 1.5.
