A design technique for realizing high Q and/or fs SC bandpass filters with reduced capa-citor spread and total capacitance is proposed. The significant reduction of capacitor spread and toul capacitance is achieved through introducing the partial positive feedback and changing the feed in capacitors in the conventional biquadratic SC filter structures. A design example of a second order high Q(=50) SC bandpass filter is given and a comparison of performance parameters among the different filter structures is given also.
