| 20100109637 | SENSOR SYSTEM AND METHOD - A sensor system for detecting the presence of one or more target substances reacting with one or more target recognition element types for producing an electrical charge detectable by a differential pair of field effect transistors that provide increased sensitivity by minimizing common mode effects on the differential pair. The differential pair is controlled by optimization algorithms in a digital signal processor that reads and store electrical characteristics of the differential pair and maintains the differential pair at optimal operating points based on continuously monitoring the differential pair. One or more target recognition element types are disbursed over a sensor gate area of the differential pair that detects one or more signature signals created by the binding of one or more target substances and the target recognition element types. The detected signature signals are compared with a library of stored signature signals for determining the identity of the target substances. | 05-06-2010 |
