Abstract
This paper has been designed with CMOS Analog-to-Digital Converter(ADC) to use a high speed embedded system. It used flash ADC with a voltage estimator and comparator for background developed autozeroing. The speed of this architecture is almost similar to conventional flash ADC but the die size are lower due to reduced numbers of comparators and associated circuity. This ADC is implemented in a $0.25{\mu}m$ pure digital CMOS technology.
