A 40 GHz CMOS PLL with -75-dBc reference spur and 121.9-fs rms jitter featuring a quadrature sampling phase-frequency detector
The high phase noise (PN) of CMOS millimeter-wave oscillators has encouraged the adoption of wide loop bandwidth for an integer-N phase-locked loop (PLL). This article proposes a quadrature sampling phase-frequency detector (QS-PFD) to disengage the tradeoff between spur rejection and loop bandwidth...
