  • Detectarea gazelor toxice prin măsurarea impedanţei peliculelor de telur 
    MOCREAC, Olga (Tehnica UTM, 2012)
    Impedance spectra of tellurium thin films with interdigital platinum electrodes have been investigated in different gaseous media. For the first time it is pointed out that tellurium films exhibit sensitivity to H2 at ...
  • Impedance characterization of Te based gas sensitive films 
    TSIULYANU, Dumitru; MOCREAC, Olga (Tehnica UTM, 2018)
    Gas sensing performance of Te films investigated by method of impedance spectroscopy is reported and discussed. The films have been prepared by thermal vacuum evaporation onto sintered alumina (Al2O3) substrates with a ...
  • Impedance meter in Cartesian coordinates 
    NICOLAEV, Pavel (Tehnica UTM, 2018)
    The paper is dedicated to the problems of automatic measurement of the impedance components in Cartesian coordinates. In paper is presented the structure and the operating principle of the impedance meter with simulated ...
  • Stabilitatea circuitelor selective pe baza convertoarelor de impedanță 
    AVRAM, I. (Technical University of Moldova, 2015)
    In this paper we study the stability of frequency selective circuits based on impedance converters. We calculated the critical amount of the setting element and the critical frequency that can be generated by selective ...
  • Utilizarea convertoarelor de impedanţă în filtre active 
    AVRAM, Ion (Technical University of Moldova, 2012)
    Active filters have a basic device of electronic communication equipment. In this paper we analyze the cheme of the impedance converter for two variants of realization. It is estimated sensitivity of the input impedance ...
