CALIBRATION CIRCUIT AND SEMICONDUCTOR DEVICE INCLUDING THE SAME |
| 摘要 |
A calibration circuit includes a pad suitable for receiving calibration data that toggles, a calibration reference voltage generation unit suitable for generating a calibration reference voltage from a median value of the calibration data, a comparison unit suitable for outputting a comparison signal by comparing the calibration reference voltage and a reference voltage with each other, and a reference voltage generation unit suitable for generating the reference voltage which is calibrated based on the comparison signal. |
