Abstract: Transistorized differential circuits include a biasing system that substantially reduces the need for resistors in the base circuits of the transistors being biased. An inductor coupled between the base of one of the transistors and a power supply forward biases the base-emitter junction of the transistor, and the other base is coupled to the same point of the power supply to bias the transistor so that the voltages at the bases of the transistors are substantially equal to each other, and are at substantially the voltage of the power supply to which the inductor is connected. This technique is applicable to balanced or unbalanced differential transistor circuits, and may be employed in amplifiers, mixers, limiters, multipliers and oscillators and in other small signal applications.
