Current-feedback magnetic multivibrator with feedback-controlled frequency compensation circuit

An improved current-feedback magnetic multivibrator having a constant frequency of oscillation is proposed. Current-feedback magnetic multivibrators are noise-proof, reliable, and highly efficient. However, the frequency of oscillation varies with the load. The proposed multivibrator can compensate the oscillation frequency by feedback control. This circuit succeeds to advantages of self-excited multivibrators.
