This article presents a 2-GHz dual-path subsampling phase-locked loop (SSPLL) with ring voltage-controlled oscillator (VCO) phase noise suppression (PNS). In addition to the conventional subsampling charge pump (SSCP), a high pass path from the subsampling phase detector (SSPD) to the low-pass filte...
