This book is organized into eight chapters. In the second chapter, an overview of
sinusoidal oscillator models is presented: we describe the positive-feedback and
the negative-resistance models. Afterwards, a survey of the automatic amplitude
control methods is presented. We focus mainly on the method that uses the intrinsic
nonlinearities of the oscillator to limit the amplitude. To conclude the single
sinusoidal oscillator modeling, we describe the frequency selectivity and introduce
the concept of the oscillator’s quality factor.
