ADC stand for analog-to-digital converter.

It is easy to understand the working principles of all ADC converters. Usually, one architecture is a natural improvement of the other architecture or one architecture uses a part of the other architecture.

The reader is encouraged to learn about ADC architectures in the following order:

flash  ->  two-step flash  ->  pipeline  ->  SAR  ->  single-slope integrating  ->  dual-slope integrating  ->  delta-sigma
