ABSTRACT:
A stabilized transistor amplifier including an amplifying transistor and its biasing circuit consisting of such elements as a power supply source, diodes and resistors in which several circuit constrants of the biasing circuit at a certain pre-selected temperature are selected so as to compensate for or cancel changes in characteristic of the amplifying transistor, the power supply source, the diodes and the resistors in combination, so that the amplifier operates stably over a wide range of the ambient temperature.
