Applications of a first-generation current conveyor in current-mode circuits

In current-mode filter circuits which utilise a single current conveyor as the only active device, the first-generation current conveyor permits feedback of the response without connecting filter elements to the output port. Complex poles can be realised in such circuits while maintaining high output impedance. The utility of this observation is illustrated by the derivation of new second-order, complex-pole, current-mode, all-pass networks that employ a single current conveyor. Laboratory and simulation results are compared
