Fibonacci sequence weighted SAR ADC algorithm and its DAC topology

This paper describes redundant successive approximation register (SAR) ADC design methods to improve reliability and conversion speed by digital error correction. Especially we show that redundant SAR ADC using Fibonacci sequence and its property called Golden ratio can be well-balanced design. We also present some simple golden-ratio-weighted DAC topologies for easy realization of the redundant SAR ADC by utilizing many interesting properties of Fibonacci sequence.
