Patent ID: 8731847

Claim:
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.
