The electromagnetic-interference effects of out-of-band signals on negative-feedback amplifiers are investigated. It is assumed that the interfering signals picked up at the input of the amplifier are dominant. Due to the nonlinear behavior of the active devices in the amplifier, unwanted dc shifts and amplitude-modulation (AM) detection may occur. Describing these effects is usually done by using the Volterra series. Although providing good results when used for analysis, methods to use the… CONTINUE READING
