Abstract:
1. An electronic circuit comprising: an adjustment module configured to (i) receive an input signal and (ii) adjust the received input signal to generate an adjusted input signal; a first amplifier configured to generate, from the received input signal, a first output signal, wherein the first output signal has, with respect to amplitude of the input signal, a nonlinear region in which amplitude of the first output signal is nonlinear with respect to the amplitude of the input signal; a second amplifier configured to generate, from the adjusted input signal, a second output signal having an amplitude; and a summation node configured to generate a sum of the amplitude of the first output signal and the amplitude of the second output signal; wherein the adjusting by the adjustment module is configured to cause the second output signal to compensate for nonlinearity in the first output signal such that the sum of the amplitude of the first output signal and the amplitude of the second output signal is linear with respect to the amplitude of the received input signal in the nonlinear region of the first output signal.
