This work presents an ultra-low phase noise and all-digital frequency generator, providing multiple output-frequencies. In a time-interleaved fashion, the proposed calibrator can continue to correct the multiple output-frequencies of injection-locked DCOs, which can change independently between 0.9 and 1.2GHz. Due to the time-interleaved calibrator, operating continuously in the background, each injection-locked DCO can maintain the excellent noise performance; the 1-MHz phase noise and the RMS-jitter at 930MHz were -132.2dBc/Hz and 310fs, and its variation across temperatures and voltages was less than 9%.
