Abstract :
The immense work presented in this paper is a high frequency sinusoidal oscillator using positive second generation current controlled conveyor (CCCII+) with minimum passive components. CCCII is implemented using single Current Feedback Operational Amplifier (CFOA) and single Operational Trans-conductance Amplifier (OTA). The frequency (time period) of CCCII is tuned to a maximum of 4 MHz using external bias current. The performance of the proposed circuit is practically verified using ICs AD844 (CFOA) and LM 13700 (OTA) and its results are included. The topology is suitable for monolithic IC fabrication.
