ABSTRACT:
Disclosed is an amplifying circuit comprising an amplifying transistor for amplifying an input signal, and a bias circuit for determining a current passing through the amplifying transistor and for determining an output voltage at the output of the amplifying transistor. The bias circuit comprising a current determining transistor for determining a current conducting through the amplifying transistor and a voltage determining transistor for determining an output voltage at the output of the amplifying transistor. The output voltage is determined independently from the determination of the current.
