DIGITAL-ANALOG CONVERSION METHOD AND DEVICE |
摘要 |
The present invention relates to a digital-analog conversion method and device for adjusting a reference current to be used in a digital-analog conversion, by using a common mode feedback device, and the digital-analog conversion method of the present invention comprises the steps of: generating a reference current by receiving a reference voltage; converting a digital signal into an analog signal by receiving the generated reference current; detecting a common mode voltage, which is the average value of a both-end voltage of the converted analog signal; comparing the detected common mode voltage with the reference voltage; generating a feedback signal on the basis of the comparison result; and adjusting the reference current according to the generated feedback signal. |
