Title: A 12-Bit ENOB 8MHz BW Noise-Shaping SAR ADC Using High-Speed Switches
Abstract: Successive approximation register Analog-to-digital converter (SAR ADC) with a passive noise-shaping modulator is an appropriate choice to increase the ENOB and save power consumption compared with conventional SAR ADC. This paper proposed a third-order noise-shaping SAR ADC with high speed switches in modulators to complete the charge sharing for reducing the time cost of noise shaping process in one sampling cycle and used a foreground calibration to calibrate the value of the capacitors in DAC array. The whole ADC can realize 12.11-Bit ENOB in 8MHz bandwidth (BW).
