The average values (with respect to the first harmonic) of transistor parameters are investigated both theoretically and experimentally as a function of the oscillation amplitude in a common-emitter configuration, when there is no bias current in the base circuit. It is shown that the effect of oscillation amplitude variation on the transistor parameters is most marked for oscillation amplitudes which are small in comparison with the collector supply voltage, and must be allowed for in designing the parameters of oscillatory circuits in the collector circuit.
