Xie, S. (author), Theuwissen, A.J.P.A.M. (author)This paper presents a CMOS image sensor (CIS) with a zoom ADC, to quantize in-pixel temperature sensors, as well as for faster readout speed of the image pixels while maintaining low quantization noise. The proposed 15 bit zoom ADC has a 4 bit Unit Capacitor Array (UCA) SAR and a 13 bit incremental 2<sup>nd</sup>-order delta-sigma ADC (DSADC)...journal article 2020

Xie, S. (author), Theuwissen, A.J.P.A.M. (author)This brief proposes a successive approximation register (SAR) analog-to-digital converter (ADC) whose readout speed is improved by 33%, through applying a digital error correction (DEC) method, compared to an alternative without using the DEC technique. The proposed addition-only DEC alleviates the ADC's incomplete settling errors, hence...journal article 2020
