| Abstract: | This paper proposes a method for the design of switched capacitor filters ( SCF ) from ana- logue ARF filters (ARF) via the line. transformation and the equivalent voltage-controlled sources trans- formation . Basic building blocks are describled for the design of any general SCF . The method suits the design of bandpass and lowpass SCF well . An example is given to illustrate the technique ' s efficiency . |
