Current Conveyor CC II with Connected Ports Y-Z

The paper deals with the classical three-port current conveyors so called second generation one (CC II). A unique application of the CC II is discussed, when the terminals Y and Z are connected together. Using this way a negative impedance converter is obtained as a suitable building block in applications given there. Specially a synthesis of the several continuous-time ARC biquadratic (second-order) filters, having or not transmission zero, is given there too.
