ABSTRACT:
A linearizing circuit is described which gives a nonlinear relation between an input and an output signal of the circuit. Such a circuit can be used to compensate for the nonlinearity in, for example, a frequency modulator. The circuit includes a nonlinear element, preferably a PIN-diode connected in a voltage divider to provide a biasing current to the element. An attenuating and an amplifying circuit are connected to the input and to the output, respectively, of the circuit. By varying the values of the attenuation/amplification and the value of the operation point of the element, the nonlinearity of the circuit can be varied.
