摘要

一个90×90全电子生物传感器阵列,用于基于电荷的DNA合成序列,在0.18μm标准CMOS工艺中实现。每个16 μm × 16 μm像素由一个集成的电荷传感电极组成,该电极连接到一个嵌入式电路,能够检测DNA聚合并同时测量电极-电解质界面电容。该传感器的检测动态范围为+90dB,当工作在8.1s/帧时,从3.3V电源消耗4 mW。

A fully-electronic charge-based DNA sequencing CMOS biochip
A 90×90 fully-electronic biosensor array for charge-based DNA sequence-by-synthesis is implemented in a 0.18μm standard CMOS process. Each 16 μm × 16 μm pixel consists of an integrated charge-sensing electrode connected to an embedded circuitry capable of detecting DNA polymerization and simultaneously measuring the electrode-electrolyte interface capacitance. The detection dynamic range of this sensor is +90dB while consuming 4 mW from a 3.3V supply when operating at 8.1s/frame.
