FLASH ANALOG TO DIGITAL CONVERTER WITH METHOD AND SYSTEM FOR DYNAMIC CALIBRATION |
摘要 |
A flash analog to digital converter and a method and system for dynamically calibrating the flash analog to digital converter. The analog to digital converter may include a track and hold circuit and a plurality of comparators. The analog to digital converter may also include an under-sampling circuit configured to convert a digitized reference signal into an under-sampled digitized reference signal with a frequency of the calibration frequency divided by a positive number M. The under-sampling circuit may be further configured to calibrate a subsequent signal based on the under-sampled digitized reference signal. |
