Abstract
This paper illustrates the use of a new class of amplifiers known as current feedback amplifiers as the active devices in sinusoidal oscillators. From theoretical analysis, supported by experiments, it is concluded that they offer improved performance regarding their opamp-based counterparts in terms of frequency accuracy, dynamic range, distortion level, and frequency span. At the same time they seem to be more flexible for the inclusion of automatic gain control schemes
