The Barkhausen well known criterion for generation of steady state harmonic oscillations is, due to its simplicity, very often used in a design of oscillators. In literature, however, there are examples of oscillator circuits that, even when this con

In this contribution we present the results of computer simulations as well as real experiments which all confirm the correctness of amendments to what is known as the Barkhausen criterion, necessary for its further application in practice [1]. The B

In this contribution we will demonstrate an extended-usage two-resonant circuit model of quartz with two LC resonators for numerical computation tuning characteristics. Real crystal resonators contain, besides a dominating resonance, other, unwanted
