Abstract-In this paper, an ultra-wideband low-noise amplifier is designed and simulated in a 0.13-μm CMOS technology for a 3-5-GHz UWB system. For ultra-wideband operation, shunt-series feedback topology is used. To improve noise performance, the amplifier employs inductive load. Biasing point variation which occurs due to the resistive feedback is fixed by adding a capacitor in series with feedback. Thus, the desirable gain is achieved with a lower power consumption. Simulations show a −3-dB gain bandwidth of 6 GHz between 2 GHz and 8 GHz, a minimum noise figure of 1.9 dB in the 3-5-GHz band, a power gain of 11.5 dB while consuming 13.9 mW.
This study is done for the purpose of analyzing the roll of teachers in the nature Character education of students from the attitudes of them by use of descriptive method of measurement kind. It's statistical community is all of the high school's teachers and students, between 180 teachers and 2939 students, in Ardakan, 1389-1390. They are selected proportional to sample method and classification of sampling coincidental method for attending in this study with 100 Teachers and 293 students. The instrument of information collecting is a questionnaire by the lickouna pattern in the mature of 5 degree likert that it's narration is accepted by masters and also it's ending is resulted by %92 cronbakh's coeffient. Analysis of information's is done in two descriptive statistical levels consist of percent , plenty , average , deviation and the inference statistic is consist of T test , T test with two in depended groups , one-side Variance and LSD consequential test. The analysis of these results is shown the roll of teachers in the nature training of students from the two perspectives of in class and outclass and the whole of sub classification was better than statistical sample of two groups at high level. There is a meaning full factors in the in cases factors base of educational field and also between attitudes of student's in the outclass perspective base on age and there is a meaningful difference also for two factors of in class and outclass base on educational field.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
