A Soft-switched Pwm Interleaved Boost-flyback Converter With Power Factor Correction

Eletrônica de Potência, 2004
This paper proposes a soft switching interleaved Boost-Flyback converter employed as a preregulator stage providing power factor correction. The use of a soft commutation cell allows the main switches to be turned on and off under null current and null ...

Directing Near‐Perfect (001) Orientation in Wafer‐Scale BiOI Thin Films via Halide‐Mediated van der Waals Stacking

Advanced Materials, EarlyView.
Our work introduces a new framework that fundamentally changes how orientation in bismuth oxyhalide systems is approached. Comprehensive experiments, backed by theoretical models, reveal the pivotal role of halide anions to modify the van der Waals stacking energies required to direct orientation. Our method enables the fabrication of near perfect (001)

A time-interleaved ADC calibration technique for spectrum monitoring applications

Microelectronics Journal, 2022
A fully background estimation and calibration technique to reduce the spur powers caused by time-interleaved ADC architecture is presented. The estimations of mismatches are succeeded using easily generated calibration signals. The implementation details for the mismatch estimations and calibrations are provided using a 2.8 GSPS ADC and a FPGA device ...

Bioengineered Interfaces for Peripheral Nerve Sensory Restoration

Advanced Materials, EarlyView.
Half of amputees abandon their prosthetics for lack of feeling. This review charts the full path from peripheral nerve injury to restored sensation, through surgical, regenerative, noninvasive, and implanted approaches, and shows how injury type and interface material properties determine which strategy can deliver naturalistic feedback, and why ...

Evolution of OLED Lamination Technology With Development of Display Form Factors

Advanced Materials Technologies, EarlyView.
This review evaluates the evolution of organic light‐emitting diode (OLED) lamination technologies alongside advancing display form factors. It contrasts optically clear adhesives and resins, highlighting uniformity control for rigid screens, bubble‐free optimization for bended architectures, and visible‐light curing for foldable layers.

Macro Memory Cell Generator for SKY130 PDK

IEEE Access
The SKY130 Process Design Kit (PDK) offers limited options for Static Random-Access Memory (SRAM) configurations, providing only three predefined memory sizes: $8\times 1024$ , $32\times 256$ , and $32\times 512$ , this poses a challenge for designers
