ABSTRACT:
A transistor amplifier having a first amplifier circuit with a first transistor having applied to its control electrode an input voltage. The ratio of the output voltage of the first transistor to the input voltage is approximately one. A second transistor circuit has a second transistor with its control electrode being directly supplied with the output voltage of the first transistor. The first and second transistors are bipolar transistors of the same type of conductivity with the respective bases used as the control electrodes.
