A new grounded-capacitor single-element-controlled CFOA-based sinusoidal oscillator circuit is presented. The circuit exploits to advantage the internal pole of a general CFOA and uses externally connected three resistors and two grounded capacitors. The frequency of oscillation and the condition of oscillation of the proposed circuit can be independently controlled. Experimental results are included.
