ABSTRACT:
A transistor biasing circuit having circuit means for biasing two amplifier transistors so as to stabilize the DC collector currents thereof regardless of variations in the factor h.sub.FE. The biasing circuit includes a biasing transistor having its emitter connected through specified resistances to the base circuits of the two amplifying transistors. In addition, a pair of series diode connected transistors are connected to the base circuit of the biasing transistor. By selecting specified values of the various resistance used in the biasing circuit arrangement, the desired stabilization technique is obtained. This circuit arrangement is particularly useful in the case of integrated circuits.
