Abstract :
It has been known that a given single or more op-amps RC sinusoidal oscillator has four distinctly different, equivalent, and stable forms. [R. Senani, Sept. 1987] [N. Boutin, Dec. 1984]. This paper´s different structure have been proposed to overcome the frequency limitations associated with uniformly distributed RC line (UR Cs) network and single pole amplifier based adjustable frequency sinusoidal oscillator. The simulation and experimental results are in reasonably good agreement with the theories and have very low harmonic distortion. This circuit can be suitable for LSI process fabrication.
