Abstract

In this article we present a method for determining the deviations ofbitweightsfor successive approximation ADC in the mainconversionmode. that is implemented using weight redundancy. The method is based on the use of weight redundancyandis based on analysis of a coding scheme in the main coding process. The method relies on the fact that a set of code combinations of ADC will be limited when applying weight redundancy. An algorithm is proposed for a successivedetermination of the deviations of the weights of the digits from the less significant bit(LSB) to the most significant bit(MSB).
