A new second generation current controlled conveyor with negative intrinsic resistance (CCCII(-IR)) based sinusoidal oscillator configuration is described. The circuit uses only grounded capacitors, which make it more suitable for monolithic integration. The function of the proposed structure is also investigated by replacing each CCCII(-IR) structure with second generation current controlled conveyor (CCCII) and found that it still operates as an oscillator. The simulation results are illustrated to verify theory. It is found that oscillator structure with CCCII gives closer frequency of oscillation to the ideal value while total harmonic distortions are less in CCCII(-IR) based structure.
