Current-feedback magnetic multivibrators are highly efficient and reliable. However, these circuits have no ability to protect themselves from overloading, and the oscillation frequency changes with the load current. We previously proposed an improved multivibrator with overload protection and frequency compensation. In this paper, the condition for cessation of oscillation and that for fixed frequency of oscillation are derived by using our model of bipolar junction transistors. This model takes account of power dissipation, because the common-emitter static forward current transfer ratio and the junction voltages depend on the junction temperature.
