Abstract :
Low-pass biquadratic filters providing a high attenuation rate in the stopband are presented. This feature achieves better high frequency parameters, even with conventional (e.g. low consumption) active elements. Analysis and improvements of the Sallen-Key filter, as well as a biquadratic filter based on the second generation current conveyor CCII are also presented. The optimisation relies on the parasitic transfer zeros elimination.
