Summary: | A quadrature clock generator is disclosed. The quadrature clock generator may include a first injection-locked oscillator, a phase interpolator, and a second injection-locked oscillator. The first injection-locked oscillator may generate a first plurality clock signals from a first reference clock signal. The phase interpolator may generate a second reference clock signal from the first plurality of clock signals, and the second injection-locked oscillator may generate a second plurality of clock signals from the second reference clock signal. A first quadrature clock signal may be selected from the first plurality of clock signals and a second quadrature clock signal may be selected from the second plurality of reference clock signals. |
