Abstract
This paper illustrates the use of term-wise Volterra analysis tool that can plot both IM3 tone and relevant 2nd order tones as vector sums of all important contributions. As an example the nonlinear distortion behaviour in a fully differential amplifier is studied, when driven either with single-ended or balanced input signal. It is shown that with single-ended drive a small tail-impedance of the differential pair generates 2nd-order distortion into the output of the first stage, and this mixes further to 3rd-order distortion in the 2nd-degree nonlinearity of the second stage.
