Abstract: Successive approximation register analog-to-digital converter (SAR ADC) has dominated the market for moderate speed and accuracy ADCs, with sampling frequency of up to 5 MHz and typical resolutions of 8 to 16 bits. While maintaining its inherent advantage of low power consumption, it faces the challenge of higher speeds and higher accuracy. The research status and advanced technology of successive approximation register analog-to-digital converter in recent years are summarized. Moreover, the sub-modules of capacitor array switching techniques, comparator and the calibration are generalized and discussed. The performance of capacitor array DACs combined with different switching strategies is compared. Comparator structures suitable for different scenarios are proposed. Calibration methods such as redundancy techniques and self-calibration techniques are discussed. Some recommendations are provided for designers to understand successive approximation register analog-to-digital converters.

Key words: successive approximation, A/D converter, switching technology, comparator, calibration
