Blood sugar level measuring device and semiconductor integrated circuit |
摘要 |
<p>A DELTA SIGMA -type analog-digital (A-D) converter is used for A-D conversion of a blood sugar level measured by a blood sugar sensor. Using the measurement result of an offset voltage in a current-voltage converter enables compensation for the offset voltage. Moreover, using the measurement result of a blood sugar level obtained with a current being applied to a dummy resistor, i.e., an element that simulates electric characteristics of the blood sugar level sensor, enables compensation for variation in the measured value between individual devices resulting from manufacturing variation. As a result, a more precise blood sugar level measuring device having higher measurement accuracy can be implemented. <IMAGE></p> |
