A new network of a variable frequency RC-sinusoidal wave oscillator using a Frequency Dependent Negative Resistor (FDNR) is proposed. The network consists of an anti-resonance circuit of an FDNR and a resistor in parallel with a negative capacitor which compensates an imperfection of the FDNR and makes the network oscillate. Both the FDNR and the negative capacitor are simultaneously realized by two cascaded Current Generalized Impedance Converters (CGIC). The practical network is constructed with two operational amplifiers and some resistors and capacitors. It is shown that if the network elements of appropriate values are used both the condition for oscillation and the output amplitude are constant over a certain frequency range of oscillation. A network using operational amplifier µA741 was examined. The frequency range of oscillation was from 10⁻² to 10⁴ Hz with a distortion factor less than 1%. The output amplitude was constant at 6.8 V from 10⁻² to 6 x 10³ Hz. An ultra low frequency oscillation of the order of 10⁻⁴ Hz was also observed.
