A general synthesis method is given for the realisation of an nth-order allpass voltage transfer function by the active RC circuit containing a minimum number of capacitors and at most n+1 current conveyors. All the current conveyors are positive, and n of them act as voltage followers. This makes the proposed circuit simple and attractive.
