METHOD AND APPARATUS FOR IDENTIFYING DEFECTS IN A CHEMICAL SENSOR ARRAYMETHOD AND APPARATUS FOR IDENTIFYING DEFECTS IN A CHEMICAL SENSOR ARRAY

摘要

In one implementation, a method for operating an apparatus is described. The method includes applying a bias voltage to place a transistor of a reference sensor in a known state. The reference sensor is in an array of sensors that further includes a chemical sensor coupled to a reaction region for receiving at least one reactant. The method further includes acquiring an output signal from the reference sensor in response to the applied bias voltage. The method further includes determining a defect associated with the array if the output signal does not correspond to the known state.
