This paper studies the synthesis of chaotic oscillators using 2-port VCCSs and capacitors. As a first step, we design a 4-D hysteresis chaotic oscillator using one linear 2-port VCCS, one hysteresis 2-port VCCS and two capacitors. In the circuit, we have confirmed theoretically that a simple periodic attractor changes into quad screw chaotic attractor as influence of the nonlinearity decreases.
