Abstract

A two-transistor (2T) pixel comprises a chemically-sensitive transistor (ChemFET) and a selection device which is a non-chemically sensitive transistor. A plurality of the 2T pixels may form an array, having a number of rows and a number of columns. The ChemFET can be configured in a source follower or common source readout mode. Both the ChemFET and the non-chemically sensitive transistor can be NMOS or PMOS device.
