VOLTAGE GENERATION CIRCUIT FOR TRIMMING VOLTAGE BY USING DIGITAL-TO-ANALOG CONVERTING CIRCUIT AND METHOD FOR THE SAME, ESPECIALLY IMPROVING TRIMMING ACCURACY OF VOLTAGE

摘要

PURPOSE: A voltage generation circuit for trimming the voltage by using the digital-to-analog converting circuit and a method for the same are provided to improve the trimming accuracy of voltage. CONSTITUTION: A voltage generation circuit for trimming the voltage by using the digital-to-analog converting circuit includes a digital-to-analog(D/A) converting circuit(12), a setting circuit(14) and a voltage generation circuit(10). The D/A converting circuit generates the voltage signal by converting the inputted digital value into the analog value. The setting circuit sets the digital value to be inputted to the D/A converting circuit. And, the voltage generation circuit is provided with a plurality of fuses so as to adjust the analog voltage values of the voltage signal into the desired analog voltage value.
