Multi-core technique is promising to achieve low phase noise and wide frequency range. However, conventional multi-core oscillators suffer large chip area, high power consumption, and limited figure of merit (FoM). This report introduces several multi-core techniques to break the tradeoff among FTR, phase noise, FoM, and area. The E-M mixed-coupling quad-core oscillator achieves four frequency bands without mode-switching-loss which exhibits FTR of 73.2% and FoMT of 201.7dBc/Hz at mm-wave band. Then, the multi-core harmonic-shaping techniques are shown to obtain higher quality factor and better shaping effect compared with single-core oscillator. The oscillator adopting the technique achieve FoM over 193 dBc/Hz at mm-wave band. Finally, the frequency synthesizers using multi-core multi-mode oscillator are introduced, which exhibit state-of-the-art jitter and frequency range.
