Kerwin-Huelsman-Newcomb circuit using current conveyors

Two equivalent circuits are generated using current conveyors to realise the same three transfer functions as in the Kerwin-Huelsman-Newcomb (KHN) biquad. Each circuit employs five current conveyors; two of them act as buffers. In both circuits, the two capacitors are grounded which is not the case in the KHN circuit.
