N2 - This paper presents a quadrature frequency synthesizer (QFS) utilizing a switched-coupled slotted inductor (SCSI)-based voltage-controlled oscillator (VCO) to simultaneously improve the reference spurs and out-of-band phase noise while achieving a wide frequency tuning range for multiband 5G mm-Wave (mmW) applications. The QFS is implemented in a 55 nm CMOS process, achieving a reference spurs of -64 to -72 dBc, an in-band phase noise of -81.7 to -87 dBc/Hz at 100 kHz offset and an out-of-band phase noise of -119.1 to -125.4 dBc/Hz at 10 MHz offset, respectively, over the entire 19.89 to 26.35 GHz frequency locking range. The RMS jitter for a 19.89 GHz carrier is 118.7 fs, corresponding to a jitter FOM of -238.47 dB. The chip occupies a die area of 1.31×2.13 mm2 including the testing pads and dissipates 101 mW of power.
