Array configuration and readout scheme
First Claim
1. A method for operating a chemical detection device comprising an array of chemical sensors arranged in rows and columns, the method comprising:
- exposing chemical sensors in the array to an analyte;
enabling a row of chemical sensors in the array, the row including a plurality of first groups of chemical sensors interleaved with a plurality of second groups of chemical sensors;
selecting a first group of the plurality of first groups of chemical sensors and a second group of the plurality of second groups of chemical sensors; and
concurrently acquiring output signals from the selected first group of the plurality of first groups of chemical sensors via a first column output circuit, and from the selected second group of the plurality of second groups of chemical sensors via a second column output circuit,wherein the first groups and the second groups are arranged in an alternating fashion, so that adjacent first groups of chemical sensors are separated by a single second group of the plurality of second groups, and adjacent second groups of chemical sensors are separated by a single first group of the plurality of first groups.

Abstract
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.
