Abstract :
A nonredundant derivation of V. Belevitch´s (1959) stability criterion for negative-conductance quasisinusoidal quasistatic oscillators is presented. The key stop step of the analysis is the definition of the asymptotic baseband impedance operator associated with the tank circuit of concern. An extension of the criterion to oscillators with both resistive and capacitive nonlinearity is provided
