For one to be a good power electronics engineer must know lot about lot. Power engineers obviously have conversion circuits and topologies. But, we also basic understanding of semiconductor physics truly understand how our switching devices work make best use them. We deep magnetics devices. all different types capacitor technologies, the characteristics each, where each fits in converter desig...

This thesis tackles the problem of data conversion in the Residue Number System (RNS). The RNS has been considered as an interesting theoretical topic for researchers in recent years. Its importance stems from the absence of carry propagation between its arithmetic units. This facilitates the realization of high-speed, low-power arithmetic. This advantage is of paramount importance in embedded ...

Direct catalytic conversion of ethanol to hydrocarbon blend-stock can increase biofuels use in current vehicles beyond the ethanol blend-wall of 10-15%. Literature reports describe quantitative conversion of ethanol over zeolite catalysts but high C2 hydrocarbon formation renders this approach unsuitable for commercialization. Furthermore, the prior mechanistic studies suggested that ethanol co...

Attrapadung (Eurocrypt 2014) proposed a generic framework called pair encoding to simplify the design and proof of security of CPA-secure predicate encryption (PE) in composite order groups. Later Attrapadung (Asiacrypt 2016) extended this idea in prime order groups. Yamada et al. (PKC 2011, PKC 2012) and Nandi et al. (ePrint Archive: 2015/457, AAECC 2017) proposed generic conversion frameworks...

Wavelength converters using quasi-phase matched LiNbO3 (QPM-LN) waveguides are recognized as key devices for future wavelength division multiplexing (WDM) systems. These converters provide unique characteristics such as the simultaneous conversion of WDM channels, a large signal bandwidth, and transparency as regards modulation format. In this review, we describe waveguide fabrication using the...

In this paper, a 2.4GHz low power downconversion mixer with high linearity for direct-conversion receivers based on a standard 0.18um CMOS technology is proposed. In the circuit design, Gilbert cell architecture and Common-Gate configuration are used. A simple buffer is applied in the IF output. Simulation results show that the mixer can operate at 2.4GHz and obtain the conversion gain of 11.08...
