Abstract
An amplifier or oscillator transistor circuit with low power consumption has a first transistor for amplification or oscillation and a biassing circuit for supplying a D.C. biassing voltage to the base of the first transistor. The biassing circuit comprises a voltage dividing resistor having an output terminal for providing a divided D.C. voltage. A second transistor has an emitter follower circuit with a base which is connected to the output terminal. Its emitter is coupled to the base of the first transistor to provide the D.C. biassing voltage. Furthermore, the first transistor means has an inverse conductive junction accompanied to the junction of the second transistor.
