  • Abstract
    Two sinusoidal oscillating structures using unity gain cells and whose controllability is provided by resistive elements are presented in this paper. In both schemes the external capacitances are grounded, thus permitting a frequency range enhancement. One of the structures is also suitable for fully integrated realization, and both can perform as active-R systems. Experimental results that confirm theoretical analysis are included
