Evaluation of Distortion Level in Analog Multipliers through DC Analysis Only
This work presents a methodology for determining figures of merit to assess distortion in analog multipliers using only DC analysis. Besides the direct determination of two dimensional integral nonlinear function, the distortion coefficients are calculated to fit the DC transfer surface and are used to estimate the total harmonic distortions for single and double input. Simulation and experimental results demonstrate that figures of merit determined either by AC or DC analysis agree with enough reliability.
