Abstract
Embodiments of a flash analog-to-digital converter (ADC) that can detect and suppress bubbles in a thermometer code of a flash ADC are provided herein. Bubbles can result in large sparkle errors, which degrade the bit error rates (BER) of flash ADCs. The present invention utilizes a bubble correction module that is configured to provide a bubble corrected one-of-N code by suppressing at least one of any two tops that are not separated by at least two levels within a one-of-N code.
