A compact adderless feed-forward incremental %$\varDelta \varSigma %$ with multiple global references for CMOS image sensors
Abstract This paper presents an adderless feed-forward incremental %$\varDelta \varSigma %$ (I%$\varDelta \varSigma %$) with asynchronous SAR (ASAR) that removes the need for in-column calibration by using global references, eliminates an additional summing amplifier and reduces the conversion time...

| 520 | |a Abstract This paper presents an adderless feed-forward incremental %$\varDelta \varSigma %$ (I%$\varDelta \varSigma %$) with asynchronous SAR (ASAR) that removes the need for in-column calibration by using global references, eliminates an additional summing amplifier and reduces the conversion time by using a multi-bit ASAR quantizer. The proposed I%$\varDelta \varSigma %$ ADC is designed in 40 nm CMOS technology and is laid out compactly in a 5 %$\mu %$m × 466 %$\mu %$m column. According to post-layout simulations, the ADC achieves an input-referred noise of 85 %$\mu %$V%$_{ rms }%$, a conversion time of 3.2 %$\mu %$s (with DCDS) and a power consumption of 230 %$\mu %$W. This results in a Walden FoM%$_{\textrm{W}}%$ of 234 fJ/conv.step and a FoM%$_{\textrm{A}}%$ = FoM%$_{\textrm{W}} \times \text {A}_{\text {ADC}}%$ of 0.54 fJ%$\cdot %$mm%$^2%$/conv.step, which demonstrates the feasibility of using the proposed architecture in CMOS image sensors. | ||

The proposed I%$\varDelta \varSigma %$ ADC is designed in 40 nm CMOS technology and is laid out compactly in a 5 %$\mu %$m × 466 %$\mu %$m column. According to post-layout simulations, the ADC achieves an input-referred noise of 85 %$\mu %$V%$_{ rms }%$, a conversion time of 3.2 %$\mu %$s (with DCDS) and a power consumption of 230 %$\mu %$W. This results in a Walden FoM%$_{\textrm{W}}%$ of 234 fJ/conv.step and a FoM%$_{\textrm{A}}%$ = FoM%$_{\textrm{W}} \times \text {A}_{\text {ADC}}%$ of 0.54 fJ%$\cdot %$mm%$^2%$/conv.step, which demonstrates the feasibility of using the proposed architecture in CMOS image sensors.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CMOS image sensors</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Analog-to-digital converters (ADCs)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Incremental</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ADC</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Switched capacitor circuits</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Readout ADCs</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Adderless feedforward</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ADC</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Asynchronous SAR (ASAR)</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Gielen, Georges</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Analog integrated circuits and signal processing</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1991</subfield><subfield code="g">118(2023), 1 vom: 08.

A compact adderless feed-forward incremental %$\varDelta \varSigma %$ with multiple global references for CMOS image sensors |
| abstract |
Abstract This paper presents an adderless feed-forward incremental %$\varDelta \varSigma %$ (I%$\varDelta \varSigma %$) with asynchronous SAR (ASAR) that removes the need for in-column calibration by using global references, eliminates an additional summing amplifier and reduces the conversion time by using a multi-bit ASAR quantizer. The proposed I%$\varDelta \varSigma %$ ADC is designed in 40 nm CMOS technology and is laid out compactly in a 5 %$\mu %$m × 466 %$\mu %$m column. According to post-layout simulations, the ADC achieves an input-referred noise of 85 %$\mu %$V%$_{ rms }%$, a conversion time of 3.2 %$\mu %$s (with DCDS) and a power consumption of 230 %$\mu %$W. This results in a Walden FoM%$_{\textrm{W}}%$ of 234 fJ/conv.step and a FoM%$_{\textrm{A}}%$ = FoM%$_{\textrm{W}} \times \text {A}_{\text {ADC}}%$ of 0.54 fJ%$\cdot %$mm%$^2%$/conv.step, which demonstrates the feasibility of using the proposed architecture in CMOS image sensors. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2023.
