GENERATION OF CURRENT CONVEYOR-BASED ALL-PASS FILTERS FROM OP AMP-BASED CIRCUITS

In this brief, it is shown that two of the recently reported voltage m ode and current mode current conveyor-based all-pass circuits can be g enerated from the well known single input op amp all-pass configuratio n, It is also found that two other voltage mode current conveyor-based all-pass circuits are related directly to the differential input op a mp all-pass structure. Several new grounded capacitor all-pass circuit s are introduced. A new universal biquad circuit which realizes comple x poles and employs a single current conveyor is also given. PSpice si mulation results are included.
