The proposed oscillators can provide 2 sinusoidal output currents with 90&amp;ordm; phase difference. It is enabled noninteractive dualcurrent control for both the condition of oscillation and the frequency of oscillation. High output impedances of the configurations enable the circuit to be cascaded without additional current buffers. The use of only grounded capacitors is ideal for integration. The circuit performances are depicted through PSpice simulations, they show good agreement to theoretical anticipation.</abstract> <index>Open Science Index 75, 2013</index> </article>
