A second order lowpass-polyphase reconfigurable filter is implemented to illustrate the technique. A 1.8 V fully differential operational amplifier in 0.18 /spl mu/ CMOS technology is used as the active element.CMOS integrated circuitsRC circuitsbiquadratic filtersdifferential amplifierslow-pass filtersoperational amplifiersradio receiversradiofrequency filterstext::conference output::conference paper not in proceedings
