Extending locked range of digital phase-locked loop by prediction estimation of states
Tongxin xuebao, 2008 A method to extend locked range of the positive zero crossing detection digital phase-locked loop（ZC-DPLL） was proposed.The nonlinear dynamical model of phase error of a non-controlled DPLL is firstly built,linearation predic-tion estimation of phase ...

Reconfigurable Ferroelectric‐Like Two‐Dimensional Electron Gas at Room Temperature
Advanced Materials, EarlyView.We demonstrate the realization of a novel ferroelectric‐like two‐dimensional electron gas (2DEG) based on the epitaxial interface between SrO‐terminate SrTiO3 and ferroeletric KNb0.5Na0.5O3${\rm KNb}_{0.5}{\rm Na}_{0.5}{\rm O}_3$ thin films. We show nonvolatile control of the transport properties enabling spatially reconfigurable devices in which ...

Optimization of Low Power Phase-Locked Loop Design [PDF]
Journal of Electrical and Electronics Engineering, 2020 This study concerns the efficient low power design of phase locked loops (PLLs). The design parameters of PLLs are; charge pump (CP), loop filter (LF), and voltage-controlled oscillator (VCO); these parameters are identifying the direct PLL performance ...

Magnetic DNA Origami Nanorotors
Advanced Materials, EarlyView.Magnetic actuation is a powerful and broadly applicable actuation mechanism due to its programmability and compatibility with biological entities. Here we demonstrate magnetic DNA origami nanorotors (MADONAs) by assembling magnetic nanocubes on DNA origami.

Chiral Altermagnetic Magnetoelectrics
Advanced Materials, EarlyView.In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.
