Method and Device for Auto-calibration of ADC |
| 摘要 |
The present invention provides a method for auto-calibration of ADC, comprising acquiring a voltage signal value of a reference voltage source; converting the voltage signal value of the reference voltage source to a digital signal value according to a preset conversion coefficient value; and comparing the digital signal value to a target value and adjusting the conversion coefficient value according to the comparing result so that the difference between the digital signal value and the target value is within an allowed margin of error. The procedure of the method for auto-calibration of ADC of the present invention is executed automatically, no professional operator is needed to calibrate manually. As such, labor cost is reduced and work efficiency is improved. |
