Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications
Advanced Materials, EarlyView.This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Low-Jitter 0.1-to-5.8 GHz Clock Synthesizer for Area-Efficient Per-Port Integration
Journal of Electrical and Computer Engineering, 2013 Phase-locked loops (PLLs) employing LC-based voltage-controlled oscillators (LC VCOs) are attractive in low-jitter multigigahertz applications. However, inductors occupy large silicon area, and moreover dense integration of multiple LC VCOs presents the ...

Design of a High-Performance High-Pass Generalized Integrator Based Single-Phase PLL
, 2016 Grid-interactive power converters are normally synchronized to the grid using phase-locked loops (PLLs). The performance of the PLLs is affected by the non-ideal conditions in the sensed grid voltage such as harmonics, frequency deviations and dc offsets
