Revision general de ADCs tipo noise shaping SAR: Fundamentos, retos y tendencias

An introduction to the study of Noise Shaping type successive approximation (SAR) analog-to-digital converters is presented, as well as a general description of the fundamentals of Noise Shaping SAR (NS SAR), its basic principles of operation and its main architectures. Open problems are addressed, fundamental challenges and main sources of error in processing circuits are reviewed, and state-of-the-art architecture developments are summarized, addressing various problems including loop filter, its passive/active implementations, and the mismatch in the elements of the DAC network, among others. Additionally, future trends and challenges are exposed.
