Novel RC sinusoidal oscillator using second-generation current conveyor

A novel second-generation current conveyor (CCII)-based resistance-capacitance (RC) sinusoidal oscillator operating over a wide dynamic range is described. The oscillation condition and the oscillation frequency can be adjusted independently by two control resistors. The circuit proposed makes use of grounded capacitors and is suitable for implementation with the commercially available integrated circuit chip AD844 from Analog Devices which implements a CCII+. The circuit enjoys low sensitivities and is suitable for integration. Experimental results are given, showing close agreement with the theoretical conclusions.
