A 10.6-mW 26.4-GHz Dual-Loop Type-II Phase-Locked Loop Using Dynamic Frequency Detector and Phase Detector
This paper reports a millimeter (mm)-wave type-II dual-loop phase-locked loop (PLL) with low-power and low-complexity design for improving jitter-power performance and power efficiency.Unlike the typical type-II single-loop PLL using a tri-state phase-frequency detector (PFD) plus a charge pump (CP) that has several limits in high-speed operation,
