Synchronous rectification in a high-performance converter design is essential for low-voltage and high-current applications because significant efficiency and power density improvements can be achieved by replacing Schottky rectification with synchronous rectification MOSFETs. Many critical parameters for synchronous rectification MOSFETs and even parasitic components in devices and printed cir...

We describe a general method for producing ultrahigh-density arrays of aligned metal and semiconductor nanowires and nanowire circuits. The technique is based on translating thin film growth thickness control into planar wire arrays. Nanowires were fabricated with diameters and pitches (center-to-center distances) as small as 8 nanometers and 16 nanometers, respectively. The nanowires have high...

This paper describes three micromachined planar inductors (a spiral type, a solenoid type, and a toroidal meander type) with electroplated nickel–iron permalloy cores which have been realized on a silicon wafer using micromachining techniques. The electrical properties among the fabricated inductors are compared and the related fabrication issues are discussed, with emphasis on the low-temperat...

This paper reviews our recent progress on arrayed waveguide gratings (AWGs) using super-high-Δ silica-based planar lightwave circuit (PLC) technology and their application to integrated optical devices. Factors affecting the chip size of AWGs and the impact of increasing relative index difference Δ on the chip size are investigated, and the fabrication result of a compact athermal AWG using 2.5...

The Substrate Integrated Waveguide (SIW) technology is a very promising technique with which we can take the advantages of both waveguides and planar transmission lines. Therefore, in [2.1-3] GHz band various microwave components and devices have been designed successfully using Ansoft HFSS software. We then proceeded to the realization of the coupler and then made measurements of the frequency...

Transfer printing integration of planar membrane devices on photonic and electronic circuits is becoming a well established technology. Typical systems incorporate single layer printed into full contact with the host substrate. In this work we present an advanced transfer print system that enables optical in non-planar geometries allows in-situ monitoring devices. We show micro-resonators air-c...

We experimentally investigate a partially shrouded sonic jet (a free-jet shielded by solid wall-extension on one side) exiting from planar nozzle at two different pressure ratio ($\zeta=4$ and $5$). show that the inherent unsteadiness shock-induced flow separation wall emitted noise in far-field is strongly coupled through series of experiments like high-speed schlieren, wall-static pressure, u...

Abstract In this paper two distinct methodologies in achieving miniaturized antennas for wireless applications are described. One method is based on defining novel topology of radiating elements that can easily be incorporated into monolithic circuits and the other method is based on embedding radiating structures within novel electromagnetic materials. Examples of extremely small planar antenn...

A quantum circuit must be preprocessed before implementing on NISQ devices due to the connectivity constraint. Quantum mapping (QCM) transforms into an equivalent one that is compliant with device’s architecture constraint by adding SWAP gates. The QCM problem asks minimal number of auxiliary gates, and NP-complete. complexity fixed parameters studied in paper. We give exact algorithm for QCM, ...
