Abstract :
An active-RC oscillator which consists of two cascaded CCII-based first-order allpass networks with unity overall feedback is described. The oscillation frequency may be controlled by means of one or two grounded capacitors. Experimental results are reported which establish the relative merits of single- or dual-element control of frequency for this oscillator
