Abstract:

An earlier report from this laboratory described the anomalous compression of a weak signal by a stronger one in a hard-saturated FET amplifier. It was shown that the amplifiers compression characteristics were not consistent with the conventional theory of hard limiters. This report recasts the hard-limiter theory in terms of a Volterra series, and shows that the previously unexplained compression characteristics are to be expected in hard-saturated multistage amplifiers. Keywords Desensitization Intermodulation distortion Nonlinear systems Saturation Volterra-series analysis.
