Design of frequency filters with active current element

By Lubomír Polášek

Abstract

In my bachelor's thesis I deal with the matter of frequency filters, how to use them, types of transferential functions and various types of approximation that can be used in the design. The next part of my thesis describes various types of active elements, either voltage or current or those working in a mixed mode. My thesis also deals with various techniques that we can use when creating frequency filters. In the final part of my thesis I introduce a scheme of an ideal current amplifier and several possible connexions of autonomous circuits with this element. Several suggestions have been shown, as well as final simulations in a OrCAD software and a possible realization of input and output impedance of a PCA element
