To improve detection quality, a chopper DDA-based analog front-end with features of low noise, high CMRR, and rail-to-rail input range is implemented. Additional temperature sensor is also included to compensate temperature drift of the biosensor. The results indicate that the detection limit is as low as 10fM. The capability to distinguish one base-pair mismatched DNAs is also demonstrated. ? 2012 IEEE. |
