Abstract: A complementary symmetry field-effect transistor amplifier employs a feedback path between the input and output terminals thereof. A second pair of complementary symmetry field-effect transistors in series with the transistors of the amplifier is employed to control the operating potentials applied to the amplifier. In one form of the circuit, the signal employed for controlling the conductance of the second pair of transistors is the output signal of the amplifier.
