Succes Sive Approximation

Understanding and minimising ADC conversion errors

The Succes-sive approximation method is the most popular technique. It is also known as Successive ap-proximation Register (SAR) technique. This technique uses binary search method. It consists of a high speed comparator, DAC (digital to analog converter), and control logic. Refer to Figure 1. Figure 1. Successive Approximation Block Diagram
