Reducing of Intermodulation Distortion in Quadrature Modulators and Demodulators by True Logarithmic Amplifier

A mathematical description of the influence of a true type logarithmic amplifier on the level of intermodulation distortion of a modulator/demodulator using a Taylor series expansion is presented in the article. Method of improving the dynamic parameters of microcircuits is described, and the results of spectral analysis of the modulator/demodulator using a logarithmic amplifier are presented.
