Abstract
Results of a detailed analysis of the errors resulting from mismatch between the dynamic magnetic characteristics of DC comparators are presented, and a way to reduce them is discussed. A modification of the comparator circuit is proposed to minimize the influence of core mismatch on the comparator operating characteristics. The proposed compensation circuit is shown to be effective in improving the operating characteristics of the DC comparator.<>
