Due to its high conversion efficiency and high power density, interleaved critical-mode converter is widely employed by modern power converters. This topology is utilized in ac-dc, dc-dc, and dc-ac converters. Because of the variable switching-frequency operation, phase-shift control is a challenge in the design of critical-mode power converters. This paper presents a triangle phase-shift control...
Cloud computing has recently become popular information technologies in enterprises. More and more enterprises tend to move from traditional enterprise information systems (EIS) to private EIS. However, few studies have addressed the switching issues, especially in large enterprises. The purpose of this study is to investigate switching intentions from traditional EIS to private cloud EIS for large...
This paper describes a 10-bit successive approximation register (SAR) analog-to-digital converter (ADC) with an energy-efficient trilevel alternate switching capacitive digital-to-analog converter (CDAC). The switching scheme of this CDAC preserves the features of the asymmetric-switching CDAC. By narrowing and smoothing the dynamic variation of DAC voltage, the switching scheme diminishes the dynamic...
Device-to-Device (D2D) communication is a proximity-based technique used by Long Term Evolution-Advanced (LTE-A) systems. When a ProSe-enabled UE in D2D communication moves across a cell boundary, seamless handover is expected. However, LTE-A does not specify D2D handover procedures, and the current LTE-A handover procedures cannot support the ProSe service continuity requirements [1]. Therefore,...
This paper presents a 10-bit successive approximation register (SAR) ADC with a detect logic for DAC switching. The proposed switching detect logic can avoid switch power wasted and reduce the impact of capacitor mismatch from the layout parasitic as well as improve the resolution performance of SAR ADC. The ADC consumes 3 uW at 0.5-V supply and 1.28-MS/s sampling rate, achieves high ENOB and FOM...
A micromechanical displacement amplifier comprising two asymmetric resonator array composites coupled by a quarter-wavelength beam has been demonstrated that permits specification of gain factor by mere (digital) selection of an appropriate ratio of the number of resonators in an input array to that in an output array. Like the method, this displacement gain circuit is a key enabler for resoswitch-based...
Colorimetric, in situ, isothermal rolling circle amplification (RCA)-based biosensor was developed as a novel, versatile nucleic acid-based amplification machine for platelet-derived growth factor (PDGF) detection. This antibody-free biosensor utilized nucleic acids immobilized on the plate and DNA aptamers to capture the target protein. As compared to the conventional fluorescence measurement [1],...
In this work, we propose a hardware-sharing P-MBIST design to test multiple memory instances with different types in one BIST design. By sharing a common address generator and controller, the area overhead is significantly reduced in comparison to existing works. A high-speed address generator with column-scan feature is also proposed for at-speed/full-speed tests. The proposed P-MBIST design can...
This paper introduces a design of high voltage pulse power supply that uses storage battery as prime power resource. This high voltage pulse power supply system can work without alternating current power supply and can be controlled by the remote control centre. Besides, some important information can be gained and displayed on the computer, such as the position, status, measured feedback of output...
