摘要：
A fully CMOS integrated carbon nanotube (CNT) sensor platform that consists of a 32X32 array of unitary CNT elements for electric bio material detection is presented. For digital conversion of the analog voltage of CNT sensor elements, a correlated double sampling (CDS) type Successive Approximation Register (SAR) analog/digital (A/D) converter has been used. Also, each sensor cell of the sensor array contains a buffer circuit which provide independent sensing signal. The CMOS chip presented in this research is applied to a DNA sensor after functionalization with a 25mer ss-DNA. Because of its small size and low power features, this sensor can be easily used for the ubiquitous sensor networks. The chip is fabricated on the basis of a 0.18mm CMOS process.
