Method and circuit for calibration of flash analog to digital converters

摘要

A system and method for correcting comparator offsets which occur during operating conditions such that static and dynamic offsets are compensated is provided. The comparator may be calibrated for normal operating conditions. The calibration may be accomplished by providing adjustability of the comparators' threshold value and providing a feedback loop for adjusting the threshold value. In one preferred embodiment, the comparator may be utilized within a flash ADC, and in a more preferred embodiment, the comparator may be utilized within a flash ADC of a read/write channel circuit.
