Abstract :
In this work it is shown that the power of the intermodulation noise of a wide-band amplifier with dynamic nonlinearities can be estimated by the total harmonic distortion (THD) with a sinusoid input signal of appropriate amplitude and frequency. The THD is, as opposed to the intermodulation noise, easy to measure and use as a design parameter
