A Low Voltage Low Power DCCII and MRC-based 2ndOrder Multiple-Output Filter

This paper presents a low voltage (plusmn1.5V) low power (800muW) multiple output filter performing low-pass, band-pass, high-pass and all pass functions. The filter has been implemented using improved differential second generation current conveyors (DCCIIs) and MOS resistive circuits (MRC) instead of resistances. Thanks to the improved topology of the DCCIIs, the proposed solution allows both to perform the fully integration in a standard CMOS technology and to have the angular frequency and the quality factor easily tunable with excellent agreement of theoretical behavior. Moreover the proposed filter presents low active and passive component sensitivities
