Generation of current conveyor-based all-pass filters from opamp-based circuits

摘要

It is shown that two of the recently reported voltage mode andncurrent mode current conveyor-based all-pass circuits can be generatednfrom the well known single input op amp all-pass configuration. It isnalso found that two other voltage mode current conveyor-based all-passncircuits are related directly to the differential input op amp all-passnstructure. Several new grounded capacitor all-pass circuits arenintroduced. A new universal biquad circuit which realizes complex polesnand employs a single current conveyor is also given. PSpice simulationnresults are included
