Chemical detection device having multiple flow channels

摘要

The described embodiments may provide a chemical detection circuit that may comprise a plurality of first output circuits at a first side and a plurality of second output circuits at a second side of the chemical detection circuit. The chemical detection circuit may further comprise a plurality of tiles of pixels each placed between respective pairs of first and second output circuits. Each tile may include four quadrants of pixels. Each quadrant may have columns with designated first columns interleaved with second columns. Each first column may be coupled to a respective first output circuit in first and second quadrants, and to a respective second output circuit in third and fourth quadrants. Each second column may be coupled to a respective second output circuit in first and second quadrants, and to a respective first output circuit in third and fourth quadrants.
