Abstract :
The aim of this paper is to describe a method of filter bank realization using the switched capacitor (SC) technique. The analysis of steps needed for this realization is performed. The correct solution requires the IIR filter bank synthesis followed by the conversion to SC circuits. Due to simplicity only the two-channel filter bank is used. The main points of the whole design procedure and key recommendations for the realization are given. The complete design of SC circuits was performed by PraCAn package in Maple program and resulted circuit structures were simulated in WinSpice. The obtained results are in agreement with theoretical derivations.
