Abstract
A method for determining a minimization factor for improving linearity of an analog-to-digital converter including a plurality of components includes the steps of: (a) Evaluating integral non-linearity response of the apparatus to identify significant departures of the response greater than a predetermined amplitude and to relate each respective significant departure with a respective identified component. (b) Determining magnitude of each significant departure. (c) Identifying a trimming factor related with each component. (d) Determining a residual gap magnitude for each significant departure. The residual gap magnitude comprises the magnitude of the respective significant departure less the trimming factor related with the identified component. (e) Determining the minimization factor as a sum of the residual gap magnitudes for a selected plurality of the identified components.
