Study, Design and Simulation of a Laboratory Module. Related to filters

Abstract

This paper presents the study, design and simulation of a laboratory module related to filters. With this laboratory platform it was accomplish a comparative study between current feedback (CFA) and voltage feedback (VFA). Because the laboratory platform has an educational role, it was presented some practical aspects of active filters measurement and also the differences between the measured values and those measured with the Spice program. The laboratory module analyzes the next aspects: choosing optimal resistance values in circuits with CFA and the comparison between OA-CFA and OA-VFA from the frequency point of view.
