This research aims to develop a teacher-oriented ICT Competency Framework for Cuban Tourism and Hotel Management School instructors, on the one hand, to have reference points(More)
—This paper addresses the design of high-Q passive inductors and differential transformers in a low-power low-noise amplifier (LNA) application. The passives quality in resonant LC tanks as well as in the matching network and degeneration inductors has been improved by balancing the trade-off between ohmic losses and Eddy current degradation. As a result,(More)
