Abstract
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.
