The described embodiments may provide a chemical detection circuit. The chemical detection circuit may comprise a pixel array, a pair of analog-to-digital converter (ADC) circuit blocks, a pair of input/output (I/O) circuit blocks coupled to the pair of ADC circuit blocks respectively, and a plurality of serial link terminals coupled to the pair of IO circuit blocks. The pixel array may comprise a plurality of chemically-sensitive pixels formed in columns and rows. Each chemically-sensitive pixel may comprise: a chemically-sensitive transistor, and a row selection device. |
