On the realization of some low-component frequency generators

Simple circuits of sinusoidal frequency generators are obtained using the frequency-dependent negative resistance (FDNR) approach. The nonideal FDNR´s employed in the realizations are canonic, and use a single operational amplifier in low-gain connection. Moreover, they are shown to be easily obtained from the well-known grounded inductance simulators. The oscillators offer active and passive component saving over Genin´s circuit.
