Semiconductor-Based Chemical Detection Device

Abstract

The described semiconductor device can include a two-transistor pixel array. Each pixel in the two-transistor pixel array can include a chemical detection pixel comprising a chemically-sensitive transistor and a row-selection transistor connected between a current source and a chemically-sensitive transistor. The source of the chemically-sensitive transistor can be coupled to a column line, and the drain of the chemically-sensitive transistor can be coupled to the source of the row selection transistor. The gate of the row selection transistor can be couple to a row line. When a row line is activated, the row selection transistor can couple the chemically-sensitive transistor to the column line.
