SAR ADC design using Golden ratio weight algorithm

This paper describes redundant successive approximation register (SAR) ADC design methods which enable high-reliability and high-speed AD conversion using digital error correction. Especially we propose to apply Fibonacci sequence and its property called Golden ratio to SAR ADC design to optimize redundant search algorithms. We present some interesting properties for well-balanced redundant SAR ADC design, as well as golden-ratio-weighted DAC topologies for its internal usage.
