A CMOS readout integrated circuit with wide dynamic range for a CNT bio-sensor array system
Abstract
We present a sensor readout integrated circuit for the CNT bio-sensor array, the heart of which is our low-power current-input continuous-time ΔΣ modulator that is capable of dynamic range extension. Experimental results show that the prototype chip, designed and fabricated in 0.18μm CMOS process, achieves a dynamic range of 87.746dB and has a readout rate of 160kHz, which guarantees 1k sample/s per each sensor. It consumes 8.94μW/cell considering the 16×10 sensors and its core area is 0.085mm2.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
