Transistor circuit including biassing circuit

Abstract From the Canadian patent

There is described s transistor circuit which is capable of reducing power consumption in voltage dividing resistors used in biasing and of suppressing temperature dependent variations in transistor characteristics. The transistor circuit has a first transistor for amplification or oscillation and a biasing circuit for supplying a D.C. biasing voltage to the base of the first transistor. The biasing circuit comprises a voltage dividing resistor having an output terminal for providing a divided D.C. voltage and a second, transistor constituting an emitter follower circuit whose base is connected, to the output terminal and whose emitter is coupled to the base of the first transistor to …
