Abstract :
The authors illustrate the use of a new class of amplifiers known as current feedback amplifiers as the active devices in sinusoidal oscillators. The well known Wien bridge oscillator has been chosen as a particular study case. From theoretical analysis, supported b experiments, it is concluded that they offer improved performance, with respect to their opamp based counterparts in terms of frequency accuracy, dynamic range, distortion level and frequency span
