An 11.0 bit ENOB, 9.8 fJ/conv.-step noise-shaping SAR ADC calibrated by least squares estimation
Garvik, Harald; Wulff, Carsten; Ytterdal, Trond (Journal article; Peer reviewed, 2017)A noise-shaping SAR ADC implemented in 28 nm UTBB FDSOI is presented. A cascaded FIR-IIR loop filter topology is used, and implemented as an inverter-based switched-capacitor circuit. The loop filter also employs input ... -
An energy efficient noise-shaping SAR ADC in 28 nm FDSOI
Garvik, Harald (Master thesis, 2015)In a noise-shaping SAR ADC, oversampling and noise shaping are used to increase the conversion accuracy beyond that the SAR exhibits alone. To implement the noise shaping, the residue voltage present at the SAR DAC plates ... -
Noise transfer functions and loop filters especially suited for noise-shaping SAR ADCs
Garvik, Harald; Wulff, Carsten; Ytterdal, Trond (Journal article; Peer reviewed, 2016)Oversampling and noise-shaping have in recent years been introduced to SAR ADCs to improve the conversion accuracy. Similar to delta-sigma ADCs, this is done by means of a feedback loop containing a loop filter. In this ...
