ABSTRACT:
There is provided a circuit which may be connected across the signal path on either the input or the output of an amplifier and which is designed to distort the signal in a manner which is complementary to the distortion contributed by the amplifier so that the resultant signal is to a large degree undistorted. The circuit utilizes a diode connected across the signal path of an amplifier with means for preventing the flow through the diode of direct current voltages appearing across the signal path. Means are provided for forward biasing the diode. The diode is selected to be of the type to have characteristics suitable for operation above 50 MHz. The diode is also selected, along with the degree of forward bias and reactive elements to provide the required compensation.
