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. our proposed PLL features a dual-loo... https://www.diegojavierfares.com/
