A Comparison of Distortion Analyses Based on Volterra Series and Steady State Algorithm
Original language description
The most accurate way for computing the distortion coefficients is to find a steady state period of the signal, and then to determine spectrum by means of fast Fourier transform. In the paper, main features of a reliable and efficient algorithm for determining the steady state are described. However, even such accelerated method often needs a time-consuming numerical integration over many periods of the faster signal. For this reason, an efficient method for a fast estimation of the main distortion coefficients is also presented which does not contain frequent imperfections in the algorithm implementations. The algorithm uses higher-order Volterra series in a simple multistep algorithm which is compatible with a typical structure of the frequency domain part of software tools. Both methods are compared by analyses of the main intermodulation products of a low-voltage low-power CMOS RF four-quadrant multiplier.
