A New Method for Polynomial Coefficient Extraction Applied to Harmonic Distortion Calculation

“…We now recall the Integral Nonlinearity Function (INLF), represented by the operator "D", which has been defined as (8,15,16),…”

“…An alternative efficient method to quantify harmonic distortion has been presented since 2002 in a number of articles (10)(11)(12)(13)(14)(15)(16). That method uses the Integral Nonlinearity Function (INLF) as an equivalent measure of the dominant kth-order harmonic distortion ratio (HD k ).…”

“…That method uses the Integral Nonlinearity Function (INLF) as an equivalent measure of the dominant kth-order harmonic distortion ratio (HD k ). Such alternative criterion has been used to successfully calculate distortion in semiconductor devices (10)(11)(12)(13)(14) and also in integrated circuits (15,16). The main advantage of using the INLF lies in its relative computational simplicity and in the fact that it does not require any kind of Fourier analysis or AC measurements.…”

Evaluating MOSFET harmonic distortion by successive integration of the I–V characteristics

“…Some integration-based methods have been proposed since 2002 [6][7][8][9][10][11][12][13] to increase the computational efficiency when calculating accurate values of distortion. Those methods, which are all closely related and based on the idea of the Integral non-linearity function (INLF) [13], circumvent dealing with AC signals avoiding the associated Fourier analysis.…”
