Abstract
This paper illustrates the use of a new class of amplifiers known as c urrent feedback amplifiers as the active devices in sinusoidal oscilla tors. From theoretical analysis, supported by experiments, it is concl uded 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 flex ible for the inclusion of automatic gain control schemes.
