In this paper, operational transresistance amplifier (OTRA) based Wien bridge oscillator is presented which uses an OTRA, two RC sections, and a buffer. The frequency of oscillation and the condition of oscillation have been derived, and the effect of device non-ideality on these parameters has also been analyzed. Further, harmonic analysis is carried out to characterize the linear performance of the proposed oscillator. Workability of the proposed Wien bridge oscillator is verified through SPICE simulations followed by experimental results. The total harmonic distortion (THD) is calculated and found to be less than 1%. Low THD value is a significant performance criterion for many high frequency applications.
