Current-mode high output impedance sinusoidal oscillator configuration employing single FTFN

In this study, a general current-mode high output impedance sinusoidal osci llator configuration is proposed. The proposed oscillator configuration use s a single four terminal floating nullor (FTFN), two capacitors and five re sistors. The oscillator configuration exhibits high output impedance which makes easy to drive loads without using any buffering devices and provide n on-interactive control of oscillation condition and oscillation frequency. The proposed topology also yields single frequency oscillators with reduced number of passive components. All of the proposed oscillators permit good frequency stability and exhibit low active and passive sensitivities. Theor etical analysis is verified with experimental results.
