These models are based on commercially available devices. They are suitable for experimental tests of current- and mixed-mode filters, oscillators, and other circuits (employing current-mode active elements) frequently used in analog signal processing without necessity of on-chip fabrication of proper active element. Several methods of electronic control of intrinsic resistance in the proposed behavioral models are discussed. All predictions and theoretical assumptions are supported by simulations and experiments. This contribution helps to find a cheaper and more effective way to preliminary laboratory tests without expensive on-chip fabrication of special active elements.en10.2478/v10048-012-0035-4info:eu-repo/semantics/openAccessIntrinsic resistancecurrent and voltage gain controlcurrent follower and amplifierbehavioral modeling2nd-Generation Current ConveyorQuadrature OscillatorArticle126255265Q3WOS:0003144582000042-s2.0-84873183933Q3
