A folded XOR gate (FXOR) phase detector (PD) is proposed for millimeter-wave (mmW) SiGe integer- $N$ phase-locked loops (PLLs) to relax the tradeoff between PLL loop bandwidth and reference spur rejection. With four current-reuse XOR gates jointly participated in phase detection, the reference spur...
