Low-Jitter Clock Multiplication: a Comparioson between PLLs and DLLs [PDF]
, 2002 This paper shows that, for a given power budget, a practical phase-locked loop (PLL)-based clock multiplier generates less jitter than a delay-locked loop (DLL) equivalent. This is due to the fact that the delay cells in a PLL ring-oscillator can consume

Observation of Dislocation Bound States and Skin Effects in Non‐Hermitian Chern Insulators
Advanced Materials, EarlyView.Experimental observation of the dislocation‐induced bound states and skin effects is demonstrated in a line‐gap non‐Hermitian acoustic lattice. By utilizing active meta‐atoms to measure the full complex spectrum and biorthogonal eigenstates, the study reveals the exceptional‐point‐driven melting of defect modes.
